Does the machine-made sand used to make concrete

Under the same conditions of water-cement ratio, the slump of machine-made sand concrete is smaller than that of river sand concrete. This is mainly because machine-made sand itself has cracks, voids and pores, and some of its particles are aggregates of mineral particles, thus increasing the sand The specific surface area of the concrete absorbs more water, which leads to an increase in the water demand of

Properties of Self-Compacting Concrete with Machine-Made ...

Thus, the substitution of machine-made sand to river sand for preparing concrete has becoming a steady tendency in concrete industry [3, 4]. Application research on machine-made sand for preparing concrete has carried out for so many years in several countries and regions. At present, machine-made sand has been applied in mortar, concrete and masonry
