High-performance concrete applying machine-made sand and preparation method of high-performance concrete
The invention relates to the field of building materials, and particularly discloses high-performance concrete applying machine-made sand and a preparation method of the high-performance concrete. The high-performance concrete applying the machine-made sand is prepared from the following components in parts by weight: 440 to 450 parts of cement, 40 to 55 parts of fly ash, 6 to 9 parts of a high-performance water reducing agent, 140 to 145 parts of water, 800 to 1000 parts of the machine-made sand, 960 to 1080 parts of stones and 5 to 10 parts of a tackifier. Each part by weight of the tackifier comprises the following components in parts by weight: 8-10 parts of coal gangue, 4-8 parts of super absorbent resin, 2-4 parts of rice hull ash and 1-4 parts of an expanding agent. The high-performance concrete applying the machine-made sand has the advantages of being good in workability and cohesiveness, small in shrinkage deformation, not prone to cracking, high in abrasion resistance and good in mechanical property and working performance.
本申请涉及建筑材料领域，具体公开了一种应用机制砂的高性能混凝土及其制备方法。应用机制砂的高性能混凝土包括以下重量份的组分：440‑450份水泥、40‑55份粉煤灰、6‑9份高性能减水剂、140‑145份水、800‑1000份机制砂、960份‑1080份石子、5‑10份增粘剂；每重量份所述增粘剂包括以下重量份的组分：8‑10份煤矸石、4‑8份高吸水树脂、2‑4份稻壳灰和1‑4份膨胀剂。本申请的应用机制砂的高性能混凝土具有和易性、粘聚性好，收缩变形小，不易开裂，耐磨性强，力学性能和工作性能好的优点。
