Anti-carbonization concrete and preparation method thereof
The invention discloses anti-carbonization concrete and a preparation method thereof, and relates to the field of concrete.The anti-carbonization concrete is prepared from, by weight, 100-200 parts of modified coarse aggregate; 50 to 90 parts of fine aggregate; 60 to 80 parts of Portland cement; 15 to 24 parts of water; 2-4 parts of a water reducing agent; 6-9 parts of a coating expanding agent; the preparation method of the coated expanding agent comprises the following steps: mixing polyethyleneimine, ethanol and an expanding agent, and carrying out ball milling to obtain the coated expanding agent. The concrete has the effect of improving the compressive strength and carbonization resistance of the concrete.
本申请公开了一种抗碳化混凝土及其制备方法，涉及混凝土领域，其由包括以下重量份的组分制备得到：改性粗骨料100‑200份；细骨料50‑90份；硅酸盐水泥60‑80份；水15‑24份；减水剂2‑4份；包膜膨胀剂6‑9份；所述包膜膨胀剂的制备方法如下：将聚乙烯亚胺、乙醇和膨胀剂混合、球磨，得到包膜膨胀剂。本申请具有提高混凝土的抗压强度和抗碳化能力的效果。
