Machine-made sand and concrete containing same
The invention discloses machine-made sand and concrete containing the machine-made sand. The machine-made sand comprises at least one of mountain flour machine-made sand, pebble machine-made sand and river sand; wherein the components of the stone powder machine-made sand comprise stone powder and stone chips in limestone, and the particle size of the stone powder is smaller than 75 microns. According to the machine-made sand, the stone powder with the particle size smaller than 75 microns is selected for matching, so that the machine-made sand is stable and adjustable in grain composition, and the grain shape can be adjusted and improved.
本发明公开了一种机制砂与含有该机制砂的混凝土。上述机制砂，包括石粉机制砂、卵石机制砂和河沙中的至少一种；其中，石粉机制砂的组分包括石灰石中的石粉以及石屑，石粉的粒径小于75μm。本申请选用粒径小于75μm的石粉进行搭配，能使得本申请的机制砂做到颗粒级配稳定且可调整，粒形也可以调整改善。
