Full-machine-made sand plastering mortar taking limestone as aggregate and preparation method thereof
The invention discloses full-machine-made sand plastering mortar taking limestone as aggregate and a preparation method of the full-machine-made sand plastering mortar. The full-machine-made sand plastering mortar taking limestone as the aggregate comprises the following components in parts by weight: 140-160 parts of cement, 770-820 parts of limestone machine-made sand, 40-70 parts of limestone powder, 0.2-0.3 part of cellulose ether, 0.005-0.01 part of an air entraining agent and 0.02-0.04 part of a thixotropic lubricant. Wherein the limestone machine-made sand and the limestone powder are prepared by crushing high-calcium stones, the fineness modulus of the limestone machine-made sand is 2.5, and the fineness modulus of the limestone powder is 0.07. The full-machine-made sand plasteringmortar taking limestone as the aggregate has the advantages of less bleeding, good workability, strong binding power after construction, no shrinkage, no hollowing, smooth and flat surface, low raw material cost, no secondary pollution, heat conduction, good heat dissipation and capability of adsorbing formaldehyde and purifying air.
本发明公开了一种以石灰石为骨料的全机制砂抹灰砂浆及其制备方法。以石灰石为骨料的全机制砂抹灰砂浆包括以下重量份的组分：140‑160份水泥、770‑820份石灰石机制砂、40‑70份石灰石粉、0.2‑0.3份纤维素醚、0.005‑0.01份引气剂、0.02‑0.04份触变润滑剂；所述石灰石机制砂和石灰石粉由高钙石子破碎制成，石灰石机制砂的细度模数为2.5，石灰石粉的细度模数为0.07。本发明的以石灰石为骨料的全机制砂抹灰砂浆具有泌水少，和易性好，施工后粘结力强，不收缩、不空鼓、表面光洁平整，且原材料成本低，不产生二次污染，导热、散热性好，能吸附甲醛，净化空气的优点。
