Seawater and sea sand recycled concrete with chloride ion curing capacity and preparation method of seawater and sea sand recycled concrete
The invention discloses seawater sea sand recycled concrete with chloride ion curing capacity. The seawater sea sand recycled concrete is prepared from the following raw materials in parts by weight: 310 to 540 parts of cementing material, 170 to 310 parts of seawater, 1000 to 1100 parts of coarse aggregate, 370 to 500 parts of fine aggregate, 1 to 5 parts of water reducing agent and 0 to 10 parts of water glass, the cementing material is composed of cement and a mineral admixture, the fine aggregate is composed of sea sand and recycled fine aggregate, and the recycled fine aggregate is undersize obtained by crushing waste concrete and sieving the crushed waste concrete through a 4.75 mm sieve; the coarse aggregate is composed of natural gravel and recycled coarse aggregate, and the recycled coarse aggregate is screen residues obtained after waste concrete is crushed and sieved through a 4.75 mm sieve. According to the invention, the waste concrete is used as aggregate to be re-applied to the concrete, the construction waste is recycled, the concept of sustainable development is met, and the prepared seawater sea sand concrete has excellent chloride ion curing capacity and good durability and mechanical properties.
本发明公开了一种具有氯离子固化能力的海水海砂再生混凝土，包括以下重量份数的原料：胶凝材料310‑540份，海水170‑310份，粗骨料1000‑1100份，细骨料370‑500份，减水剂1‑5份，水玻璃0‑10份；所述胶凝材料由水泥和矿物掺合料组成，细骨料由海砂和再生细骨料组成，再生细骨料是由废弃混凝土破碎后过4.75mm筛得到的筛下物；所述粗骨料由天然碎石和再生粗骨料组成，再生粗骨料是由废弃混凝土破碎后过4.75mm筛后的筛余物。本发明将废弃混凝土作为骨料重新应用到混凝土中，对建筑垃圾进行了循环利用，符合可持续发展的理念，制得的海水海砂混凝土具有优良的氯离子固化能力，耐久性和力学性能比较好。
