In order to achieve its characteristic low density, light concrete is constructed from lightweight coarse materials such as shales, clays, or slates. Compared to regular-weight concrete, structural lightweight concrete has an in-place density of 90-115 pounds per square foot. For modern structures with minimum foundation cross sections, lightweight concrete is perfect. A feasible alternative to conventional concrete, it is widely used in the construction of slimline foundations. There are many facts of the availability of lightweight concrete in Selangor.
Despite this, lightweight concrete can have a higher compressive strength of 7000 to 10,000 psi. If the density of the concrete mix is compromised, extra pozzolans and water-reducing admixtures must be added to the concrete to compensate for this.
Lightweight concrete, on the other hand, has a larger water content than ordinary concrete. It takes longer for cement to dry when it contains porous aggregates, thus they are pre-soaked in water before being placed into the cement.
Due to the presence of denser particles, conventional concrete might weigh between 140 and 150 lbs/ft3. Consequently, many people feel that conventional concrete is cheaper than LWC. As a result, the overall cost of projects produced with standard concrete is higher. As a result, LWC remains a cost-effective construction material, particularly for larger projects.
Construction materials such as lightweight concrete are flexible and easily transportable, and they require little support from other elements such as steel or extra concrete to be effective. This makes it more cost-effective, especially for larger construction projects that require more resources.
Its low thermal conductivity and fire resistance make LWC an appropriate material to use for protecting against heat damage. It’s unlikely that structures constructed with LWC will collapse despite their lower density LWC, on the other hand, shrinks less than standard concrete and is more resistant to rot and termites. However, there are several limits to LWC. It takes longer for it to dry out because it has a larger water content. Over-watering can also lead to laitance layers, while cutting back on water to make up for this can result in a weaker mixture.
Due to the porous nature of LWC, it is difficult to properly put the combination. When LWC is mixed incorrectly, the cement tends to separate from the aggregates. As an alternative to conventional concrete, lightweight concrete is a cost-effective option, especially since it does not affect the structure’s strength. Porosity also affects thermal conductivity, which makes LWC ideal for projects that require heat damage protection.
The unforeseen implications of lightweight concrete mix design and manufacture are described. On the mechanical qualities of structural lightweight concrete, some of the information in existing European concrete standards is questioned. Here you’ll find the newest developments in the field of ultra-lightweight concrete. There’s a new technique to increase the variety of applications of lightweight concrete, called infra-lightweight concrete, that’s based on prior knowledge and case studies.
