Special machine-made sand composite material for composite floor component and preparation method thereof
The invention discloses a special machine-made sand composite material for a composite floor component. The special machine-made sand composite material is characterized by being prepared from the following components in parts by weight: 870 to 930 parts of rubble, 165 to 195 parts of fine stone, 490 to 520 parts of machine-made sand, 50 to 90 parts of medium sand, 380 to 420 parts of superfine sand, 320 to 480 parts of cement, 80 to 100 parts of water and 4.5 to 6.5 parts of an additive. The invention further provides a preparation method of the special machine-made sand composite material for the composite floor slab component. The machine-made sand composite material special for the composite floor slab component is good in comprehensive performance, good in durability and excellent in mechanical property, and has high slump loss resistance, bleeding resistance and frost resistance and good adaptability to cement.
本发明公开了一种叠合楼板构件的专用机制砂复合材料，其特征在于，包括按重量份计的如下各组分制成：粗石870‑930份、细石165‑195份、机制砂490‑520份、中砂50‑90份、特细砂380‑420份、水泥320‑480份、水80‑100份、外加剂4.5‑6.5份。本发明还提供了一种所述叠合楼板构件的专用机制砂复合材料的制备方法。本发明公开的叠合楼板构件的专用机制砂复合材料综合性能佳，耐用性好，机械力学性能优异，具有高保坍，抗泌水、抗冻能力强，与水泥的适应性好。
