Whether you are looking for a building material that can be used for residential, commercial or industrial purposes, concrete Malaysia has a wide range of options that you can choose from. From precast concrete to off-form concrete, you can find the product you need to get the job done.
Precast concrete
Founded in January 2010, Precast Concrete Pte Ltd is a construction company that specializes in manufacturing precast concrete products. Its products are used in commercial, industrial, residential, and civil engineering projects.
Precast concrete products include structural wall panels, floors, beams, columns, retaining walls, and foundations. Various precast concrete building components can be manufactured at a factory or at site, depending on the customer’s needs.
There are many advantages of using precast concrete components. They save time and money in construction and are environmentally friendly. Compared to traditional construction methods, precast concrete reduces the need for site labour. Moreover, the components can be cast in sheltered environments, which can increase energy efficiency.
Precast concrete can also be used to construct smaller structures. In fact, some precast products can lend themselves to special slings and clamps.
Precast concrete can also be used for water and wastewater projects. Products such as dry wells, septic tanks, and pipelines are manufactured using precast concrete. It is environmentally friendly and can be reused many times.
Precast concrete is often used for large-scale commercial buildings and government infrastructure projects. There are also many design options available in the precast concrete industry. In particular, it is important to choose the right spec for the project.
Precast concrete components are also used for smaller structures such as fireplace mantels and curtain walls. In addition, precast concrete can be used for utility structures such as trenches, light pole bases, and meter boxes. These structures protect important connections and control devices, as well as being environmentally safe.
One of the most important factors in the production of precast products is curing. In order to achieve quality, precast products need to be cured under the right conditions. These include moisture content and adequate humidity. The product must also be protected from the sun and wind.
Admixtures for cement and concrete
Various concrete admixtures are used to improve the properties of concrete. These admixtures range from liquid to dry powders. These admixtures can enhance the permeability, slump, flowability, and strength of concrete. These admixtures are usually added during mixing or batching. The type of admixture that is used depends on the needs of the construction project.
Water reducers are used to reduce the amount of cement in concrete. These admixtures are also used to reduce the water-cement ratio. The effectiveness of these admixtures depends on the amount of water, the type of cement, and the slump of the concrete.
Accelerators are admixtures that accelerate the early age strengths of the concrete. They also shorten the set time. These admixtures are often based on calcium chloride.
Crystalline admixtures are used to fill the capillary pores in concrete. They also increase the compressive strength and flexural strength of concrete. Crystalline admixtures are usually added during batching of concrete.
Air entraining admixtures are incorporated during the mixing process to place microscopic air bubbles in the concrete. This admixture is used to increase the durability of the concrete and to reduce cracking. These admixtures are usually used in small quantities.
High-reactivity metakaolin admixture is derived from kaolinite, a clay mineral. It is highly processed aluminosilicate pozzolanic mineral. It is used to reduce permeability, increase compressive strength, and improve flowability. It is also used in a variety of applications including highways, bridges, and parking structures.
Shrinkage reducers are liquid admixtures that are used to reduce the drying shrinkage and cracking of concrete. These admixtures are used to reduce the amount of water that evaporates from the concrete after it is cured.
Off-form concrete
Among the many construction materials that are on the market, off-form concrete is one of the most cost-effective options. The material is a mix of water, aggregate and hydraulic cement that is poured into a form. The result is a remarkably durable and attractive material that can be used to build structures such as driveways, pathways and slabs. Alternatively, it can be exposed to add to the raw industrial aesthetic of a building.
Off-form concrete can be produced on-site or off-site, depending on the needs of the project. Off-site concrete is also known as precast concrete. Depending on the requirements of the project, the cost of off-form concrete can range from a few thousand dollars to several hundred dollars per cubic meter. This material can be used to create limitless shapes and textures. It can also be used to create a plethora of visual effects. For example, it can be used to create a series of stairs. This type of off-form concrete can be used to create a kitchen island, a bench or even built-in seating. It can also be used to create countless other types of structures. It is also used to form the structural walls of a building.
The most effective way to create off-form concrete is to make it on-site. The process can be simplified by using formwork. Formwork can be made from aluminum, steel or wood. Depending on the project, the materials that are used can also affect the cost. In fact, there are even companies that will offer a free quote on off-site construction.
Using a form-grade concrete can also be a great way to save money. The material is also highly durable, making it ideal for projects that involve heavy equipment.
Waterproofing methods
Using waterproofing methods for concrete Malaysia is important because water can cause damage to structures. If left untreated, water can leak through cracks and cause reinforcing steel corrosion. Additionally, water can damage surfaces if exposed to sunlight.
There are several waterproofing methods available in Malaysia. One of the most common methods is cementitious waterproofing. Cementitious waterproofing uses cement-based polymer coatings to protect concrete from water. This type of waterproofing is generally used for balconies, car porches, and rooftops.
Another common waterproofing method is the use of bituminous membrane. Bitumen is a petroleum product, usually obtained from crude oil. It is a hydrophobic and flexible material, making it an attractive option for waterproofing concrete. However, bitumen is not an environmentally friendly material.
Cementitious membranes are semi-flexible and are commonly used for internal areas. They are also easy to apply. They are also able to handle heavy traffic flow.
Another type of waterproofing method is crystalline coating. This technique involves the formation of tiny crystals on the concrete surface. The crystals diffuse through the surface and provide waterproofing in its own matrix. It is a good solution for concrete structures because it is easy to apply, and provides a watertight barrier to the surface.
Other types of waterproofing methods include sheet membrane systems and fluid-applied type. Sheet membrane systems are cheaper than fluid-applied type systems. They are also more suited for vertical and protruding areas, as well as small, confined spaces. However, these types of systems also have their disadvantages.
Waterproofing materials have a large impact on humidity. Therefore, manufacturers should provide the proper RH control factors for their products. These factors can be achieved by using electrical facilities, exhaust fans, and humidifiers.
Batu 6 Bridge
Located in Gerik, Perak, Batu 6 Bridge is the longest single-span road bridge in Malaysia and has been named as one of the top ten bridges in the world by PCI (Past Council of International Engineering). It also has been awarded the PCI Design Award for Best International Transportation Structure.
Batu 6 Bridge is constructed using UHPC (Ultra-High-Performance Concrete), a high-performance concrete which has more than 10 times the compressive strength of conventional concrete. UHPC is also much less prone to bending than conventional concrete. The lower risk of failure enables the bridge to be built in a shorter time.
UHPC can be used to build long span bridges in rural areas. This can reduce construction costs and improve service life. Compared to conventional steel or concrete, UHPC is also cost competitive.
In Malaysia, UHPC has been used for construction of bridges for more than 20 years. There are currently 84 UHPC bridges in the country, including road bridges, pedestrian bridges and a pedestrian bridge in Negeri Sembilan. A further 10 bridges are in construction. Several single-span UHPC bridges are being planned for flood-prone areas.
Unlike conventional concrete, UHPC does not contain any chemicals that are deleterious to the matrix or composition. It also has twice the resistance to abrasion than conventional concrete. It has also been proven to be more durable under extreme weather conditions. UHPC does not require active steam to initiate curing.
UHPC can also reduce the cost of temporary falsework and supports, and it also has a much shorter construction period. It also allows for a more sustainable process and less environmental impact. It also reduces the need for in-situ decking.
