The invention discloses a high-strength easily-compatible concrete reinforcing agent which comprises the following raw materials in parts by weight: 12-16 parts of isopentenol polyoxyethylene ether, 22-26 parts of sodium lignin sulfonate, 2-4 parts of graphene dispersion liquid, 1-3 parts of modified starch, 1-3 parts of a polycarboxylate superplasticizer, 1-3 parts of an early strength agent, 2-4parts of an emulsifier and the like. According to the invention, the strength of concrete can be increased by 8%-20%, the workability, bleeding resistance, no segregation and easy pumping of the concrete can be effectively improved, the frost resistance and carbonization resistance are greatly improved, and the concrete reinforcing agent is non-toxic, harmless, pollution-free, radioactivity-freeand free of chloride ions, alkali and the like.
本发明公开了一种高强度易相容的混凝土强效剂，按重量份数计，包括异戊烯醇聚氧乙烯醚12‑16重量份、木质素磺酸钠22‑26重量份、石墨烯分散液2‑4重量份、改性淀粉1‑3重量份、聚羧酸减水剂1‑3重量份、早强剂1‑3重量份、乳化剂2‑4重量份等原料。本发明能够增加混凝土强度8％‑20％，能有效改善混凝土的和易性、抗泌水、不离析、易泵送，并且在抗冻性及抗碳化性能上有很大提高，无毒、无害、无污染和无放射性，不含氯离子及碱等。
