CONTROLLED LOW STRENGTH MATERIAL COMPOSITION FOR CONSTRUCTION AND MAINTENANCE OF PAVEMENTS

摘要

ABSTRACT In one aspect, a controlled low-strength material (CLSM) for pavement maintenance comprises, a cement, a ground granulated blast furnace slag (GGBS), a quarry dust and water. The cement and GGBS forms a binder composition of CLSM. The quarry dust forms a fine aggregate in the CLSM. A first quantity of water added to the mixture forming the CLSM a flowable substance with a first flowability. The quarry dust forms at least 37% and GGBS forms at least 35% of CLSM composition. In an embodiment, the water forms at least 25% of CLSM composition. The CLSM composition forms a circular shape of diameter at least 150mm, when spread on a flat surface. In an embodiment, the CLSM of 5400 gms comprise atleast 100gms of cement, 1900gms of GGBS, 2000gms of quarry dust and 1400gms of water.
