Investigation Of The Mix Ratio Design Of Lightweight Aggregate Concrete

This article reports on the use of a mix ratio design for lightweight aggregate concrete. The mix ratio design is based on the loose volume of light and coarse aggregate per cubic concrete, then balanced according to the dry apparent specific gravity of concrete with the design requirements. The authors note that although the principle of water-cement ratio is suitable for lightweight aggregate concrete, it is very difficult to measure the saturated surface-drying apparent specific gravity of aggregate. The authors also discuss the concept of a concrete filler coefficient, the theoretical formula of sand-aggregate ratio, and the quasi-principle of stationary water consumption.
