Anti-mud additive suitable for machine-made sand concrete and compounding method thereof
The invention relates to an anti-mud additive suitable for machine-made sand concrete and a compounding method thereof. The anti-mud additive comprises the following components in parts by weight: 30-50 parts of a lignosulfonate water reducing agent, 20-35 parts of a viscosity reduction type polycarboxylic acid water reducing agent, 0.2-0.25 part of a defoaming agent and 20-45 parts of water. Thecompounding method specifically comprises the following steps: mixing and compounding the mud-resistant admixture and the machine-made sand concrete, wherein the performance of the machine-made sand concrete can be changed by changing the adding sequence of the lignosulfonate water reducing agent. Compared with the prior art, the anti-mud additive can be used for improving the mud resistance of the machine-made sand concrete, and the cohesiveness and compressive strength of the machine-made sand concrete can be remarkably improved.
本发明涉及一种适用于机制砂混凝土的抗泥型外加剂及其复配方法，所述抗泥型外加剂包括以下组分及重量份含量：木质素磺酸盐减水剂30‑50份、降粘型聚羧酸减水剂20‑35份、消泡剂0.2‑0.25份和水20‑45份。复配方法具体为将抗泥型外加剂与机制砂混凝土进行混合复配，可通过改变木质素磺酸盐减水剂的加入顺序而改变机制砂混凝土的性能。与现有技术相比，本发明可用于提高机制砂混凝土的抗泥性能，能显著提高机制砂混凝土的黏聚性和抗压强度。
