Sidewalk and construction process thereof
The invention relates to a sidewalk and a construction process thereof, and relates to the technical field of building construction. The sidewalk comprises high-strength concrete bricks, M10 cement mortar, a C20 concrete cushion layer, a broken stone cushion layerand pond slag from top to bottom; the high-strength concrete brick is prepared from the following raw materials in parts by weight: 180-200 parts of ordinary Portland cement; 1100 to 1200 parts of a coarse aggregate; 160 to 180 parts of an active admixture; 30 to 50 parts of rubber powder; 20 to 40 parts of reinforcing fibers; 10 to 30 parts of polyvinyl alcohol; 4-8 parts of a polycarboxylate superplasticizer; 180 to 220 parts of water; wherein the coarse aggregate comprises 20-40% of natural macadam and 60-80% of a modified recycled aggregate. The recycled aggregate is modified to enhance the strength of the recycled aggregate, thereby enhancing the strength and widening the application range of the recycled concrete.
本发明涉及涉及一种人行道及其施工工艺，涉及建筑施工的技术领域，其自上而下包括高强度混凝土砖、M10水泥砂浆、C20砼垫层、碎石垫层和塘渣；所述高强度混凝土砖包括以下重量份原料制成：普通硅酸盐水泥180‑200份；粗集料1100‑1200份；活性掺合料160‑180份；橡胶粉30‑50份；增强纤维20‑40份；聚乙烯醇10‑30份；聚羧酸减水剂4‑8份；水180‑220份；所述粗集料包括20‑40%的天然碎石和60‑80%的改性再生骨料。通过对再生骨料进行改性，用以提高再生骨料的强度，从而提高了再生混凝土的强度和使用范围。
