Pervious concrete with high freeze-thaw resistance and production process
The invention discloses pervious concrete with high freeze-thaw resistance and a production process, and the pervious concrete with high freeze-thaw resistance is prepared from the following raw materials in parts by weight: 7-10 parts of water, 30-40 parts of Portland cement, 10-15 parts of pebbles, 65-75 parts of coarse aggregate, 20-30 parts of fly ash, 4-6 parts of a water reducing agent, 5-7 parts of a reinforcing agent, 7-10 parts of an ice inhibitor, 3-5 parts of a corrosion inhibitor, 5-7 parts of an adhesive agent, 2-3 parts of dry ice, 2-4 parts of a curing agent, 30-35 parts of a PE material, 4-5 parts of an anti-sticking agent. The preparation method comprises the following steps: reinforcing the coarse aggregate, adding theadhesive agent into a high-speed mixer, then adding the curing agent, heating to 80-90 DEG C, stirring and mixing for 10-15 minutes, stopping stirring, then adding the dry ice, and stirring for 4-16 minutes. According to the pervious concrete with the high freeze-thaw resistance and the production process, gaps among coarse aggregates can be increased, internal pervious gaps are increased after the concrete is solidified, pervious use is more effective, the impact resistance of bottom layer concrete is improved through the material characteristics of a PE material, and the original strength characteristic of the concrete is not affected.
本发明公开了一种抗冻融性强的透水混凝土及生产工艺，该抗冻融性强的透水混凝土由以下重量份数的原料制备而成：水7‑10份、硅酸盐水泥30‑40份、石子10‑15份、粗骨料65‑75份，粉煤灰20‑30份、减水剂4‑6份，增强剂5‑7份，抑冰剂7‑10份，阻锈剂3‑5份，胶连剂5‑7、干冰2‑3份、固化剂2‑4份、PE材料30‑35份，防粘剂4‑5份，加强粗骨料，将胶连剂加入高速混合机中，再加入固化剂，加热至80‑90℃，搅拌混合10‑15min，停止搅拌后再加入干冰搅拌4‑16min。本发明所述的一种抗冻融性强的透水混凝土及生产工艺，能够增加粗骨料之间的间隙，在混凝土凝固后增加内部透水缝隙，更有效的进行透水使用，通过PE材料材料特性，提高底层混凝土的抗冲击性，并不影响混凝土原有的强度特性。
