High-strength anti-crack concrete and preparation process thereof
The invention relates to high-strength anti-crack concrete and a preparation process thereof. The high-strength anti-crack concrete is prepared from the following raw materials in parts by weight: 180-200 parts of ordinary Portland cement; 1180-1220 parts of coarse aggregate; 600-640 parts of fine aggregate; 200-240 parts of an active admixture; 8-12 parts of a polycarboxylate superplasticizer; 30-50 parts of fiber filler; 4-8 parts of a slow-release alkaline agent; 180-200 parts of water. The fiber filler is added to toughen the concrete, so that the anti-cracking effect and strength of the concrete are improved.
本发明涉及一种高强度抗裂混凝土及其制备工艺，其包括以下重量份计原料制得：普通硅酸盐水泥180‑200份；粗集料1180‑1220份；细集料600‑640份；活性掺合料200‑240份；聚羧酸减水剂8‑12份；纤维填料30‑50份；缓释碱剂4‑8份；水180‑200份。通过加入有纤维填料，用以对混凝土增韧，从而提高混凝土的抗裂效果和强度。
