What Is Lightweight Aggregate Concrete And Its Uses?

The structural concrete density can be easily achieved with the use of lightweight aggregate concrete. The lightweight concrete is also known to absorb very little water and can maintain the low density. It is known to be equal or lower than that of normal concrete. It also has a high degree of saturation. The lightweight aggregate concrete, structural lightweight concrete

09/10/2021  Despite the undoubted advantages of using lightweight concrete, its actual use for structural elements is still relatively small in comparison to ordinary concrete. One of the reasons is the wide range of densities and properties of lightweight aggregates available on the market. As a part of the research, properties of concrete based on sintered fly ash were

Lightweight Aggregate Concrete - ScienceDirect

01/01/1992  Structural lightweight aggregate concretes are suitable for high fire ratings and in this respect are superior to normal weight concretes since they (a) exhibit a lower strength reduction at high temperature, (b) provide more insulation and (c) have lower thermal expansions which result in less spalling. Benefits can be achieved using lightweight aggregate concrete

Lightweight concrete

The required properties of the lightweight concrete will have a bearing on the best type of lightweight aggregate to use. If little structural requirement, but high thermal insulation properties, are needed then a light, weak aggregate can be used. This will result in relatively low strength concrete.
