High-crack-resistance low-heat Portland cement and preparation method thereof
The invention relates to high-crack-resistance low-heat Portland cement and a preparation method thereof. Belongs to the technical field of building materials. The cement comprises the following components in parts by weight: 81-92 parts of cement clinker, 2-7 parts of gypsum, 1-4 parts of an exciting agent and 5-17 parts of an adjusting material, the cement clinker comprises the following mineral components in percentage by weight: 30%-40% of tricalcium silicate, 35%-45% of dicalcium silicate, 3%-8% of tricalcium aluminate and 14%-17% of tetra calcium aluminoferrite, and the adjusting material comprises the following components in percentage by weight: 35%-46% of bentonite, 31%-40% of super absorbent resin, 10%-23% of hollow glass beads and 6%-18% of an alcohol amine aid. The comprehensive performance of the low-heat Portland cement can be remarkably improved, so that the cracking risk of the concrete in a harsh and complex environment is reduced.
一种高抗裂型低热硅酸盐水泥及其制备方法。属于建筑材料技术领域。按重量份计包括：81‑92份水泥熟料2‑7份石膏和1‑4份激发剂，还包括5‑17份调节材料；所述水泥熟料中矿物成分按重量百分比包含30‑40%的硅酸三钙、35‑45%的硅酸二钙、3‑8%的铝酸三钙和14‑17%的铁铝酸四钙，所述调节材料按重量百分比计包括：35‑46%的膨润土、31‑40%高吸水性树脂、10‑23%空心玻璃微珠和6‑18%醇胺助剂。本发明可实现低热硅酸盐水泥综合性能的显著提升，以降低严酷复杂环境下混凝土开裂风险。
