The invention discloses concrete using a synergist. The concrete is prepared from the following components in parts by weight: 100 to 150 parts of cement, 15 to 20 parts of fly ash, 300 to 400 parts of machine-made sand, 280 to 320 parts of gravel, 120 to 150 parts of recycled aggregate, 20 to 30 parts of a water reducing agent, 20 to 30 parts of the synergist and 70 to 80 parts of water, wherein the synergist comprises the following components in parts by weight: 30-35 parts of a cement reinforcing agent, 15-20 parts of calcium carbonate, 6-8 parts of calcium lignosulphonate, 3-5 parts of sodium nitrate, 8-10 parts of maleic anhydride, 3-5 parts of mercaptoethanol, 10-12 parts of nano silicon dioxide and 6-8 parts of hydroxyethyl cellulose; the recycled aggregate is prepared from crushed building wastes. According to the concrete using the synergist provided by the invention, the strength and durability of the concrete can be remarkably enhanced, and the use amount of cement in the concrete can be reduced.
本发明公开了一种使用增效剂的混凝土，包括按重量份数计的如下成分：水泥100‑150份、粉煤灰15‑20份、机制砂300‑400份、碎石280‑320份、再生骨料120‑150份、减水剂20‑30份、增效剂20‑30份、水70‑80份；其中，增效剂包括按重量份数计的如下成分：水泥增强剂30‑35份、碳酸钙15‑20份、木质素磺酸钙6‑8份、硝酸钠3‑5份、马来酸酐8‑10份、巯基乙醇3‑5份、纳米二氧化硅10‑12份、羟乙基纤维素6‑8份；所述再生骨料采用粉碎建筑废弃物制备而成。本发明提供的使用增效剂的混凝土，可以显著增强混凝土的强度和耐久性标，且可减少混凝土中水泥的用量。
