Porous vegetation concrete capable of improving vegetation performance
The invention discloses porous vegetation concrete capable of improving vegetation performance. The porous vegetation concrete is prepared from the following raw materials in parts by mass: 180-200 parts of cement, 1200-1400 parts of recycled coarse aggregate, 8-15 parts of emulsion and 40-70 parts of water, the emulsion is composed of a styrene-acrylic emulsion, a VAE emulsion and a styrene-butadiene emulsion. The mixed emulsion composed of the styrene-acrylic emulsion, the VAE emulsion and the styrene-butadiene emulsion is added, so that the hydration reaction of C2S can be delayed, and further the hydration of sulphoaluminate water cement is delayed; meanwhile, in the hydration process, Al (OH) 3 formed by the modified cement paste doped with the emulsion is reduced along with the increase of the mixing amount of the emulsion, so that the pH value of the cement is reduced. The recycled aggregate plant-growing concrete modified by the emulsion can greatly reduce the pH value of a pore solution, improves the plant-growing performance of the concrete, can adapt to the growth of green plants, can achieve the effects of greening the environment and restoring ecology for a long time, and also can improve the compressive strength of the plant-growing concrete.
本发明公开了一种能够提高植生性能的多孔植生混凝土，由如下质量分数的原料制成：水泥180‑200份、再生粗骨料1200‑1400份、乳液8‑15份和水40‑70份；所述乳液由苯丙乳液、VAE乳液和丁苯乳液组成。本发明加入苯丙乳液、VAE乳液和丁苯乳液组成的混合乳液能够延缓C2S的水化反应，进而延迟硫铝酸盐水泥水化；同时在水化过程中，掺杂了乳液的改性水泥浆体形成的Al(OH)3，随着乳液掺量的增加而减少，使水泥的酸碱度降低。经乳液改性后的再生骨料植生混凝土可以极大限度降低孔隙溶液pH值，提高混凝土植生性能，能够适应绿色植物生长，可长期起到绿化环境、修复生态的效果，同时还能提高植生混凝土的抗压强度。
