A platform for research: civil engineering, architecture and urbanism
The invention discloses a concrete block with good waterproof and heat insulation effects. The concrete block is composed of the following components in percentage by weight: 18-25% of mullite-SiC-andalusite brick reclaimed material, 20-28% of cement, 3-5% of anti-freezing and waterproof agent, 12-18% of semi-hydrated phosphogypsum, 0.1-0.3% of gas generating agent, 1.5-3.2% of terylene needled felt, 0.1-0.2% of naphthalene water reducer and the balance of fly ash. A small amount of anti-freezing and waterproof agent composed of ethylene glycol, styrene-acrylic emulsion and redispersible latexpowder is added into the concrete block, and the styrene-acrylic emulsion, the redispersible latex powder and Portland cement in the anti-freezing and waterproof agent can form a gel system with a good waterproof effect under the foaming effect; and the polyester needled felt is added, so that ethylene glycol can be dispersed more uniformly, and the anti-freezing effect is remarkably improved. The concrete block prepared by the invention is excellent in waterproof and anti-seepage performance and good in anti-freezing effect.
本发明公开了一种防水隔热效果好的混凝土砌块,由以下重量百分比的成分组成:硅莫红砖回收料18‑25%、水泥20‑28%、防冻防水剂3‑5%、半水磷石膏12‑18%、发气剂0.1‑0.3%、涤纶针刺毡1.5‑3.2%、萘系减水剂0.1‑0.2%和粉煤灰余量。该混凝土砌块加入了少量由乙二醇、苯丙乳液和可再分散性乳胶粉组成的防冻防水剂,该防冻防水剂中的苯丙乳液和可再分散性乳胶粉与硅酸盐水泥在发泡效果下可以形成防水效果好的凝胶体系;加入涤纶针刺毡可以使乙二醇分散的更加均匀,显著提升了防冻效果。本发明制成的混凝土砌块不仅防水、抗渗性能优越,而且防冻效果好。
