Premixed high-performance concrete admixture and concrete using admixture
The invention relates to the technical field of concrete admixtures, in particular to a premixed high-performance concrete admixture and concrete using the admixture, and the premixed high-performance concrete admixture is prepared from the following raw materials in parts by weight: 40-90 parts of fly ash; 8-20 parts of modified rubber powder; 5-10 parts of a sawdust activated carbon-early strength material; 70 to 100 parts of a polymer; the modified rubber powder is prepared by modifying rubber powder with a silane coupling agent and then coating the modified rubber powder with a low-temperature-resistant material; the sawdust activated carbon-early strength material is prepared from sawdust activated carbon and an early strength agent. The invention designs and prepares the high-performance concrete admixture with impact resistance, prolonged service life and durability, and applies the admixture to concrete to obtain the high-performance concrete with impact resistance and long service life.
本发明涉及混凝土掺合料技术领域，具体来说是一种预拌高性能混凝土掺合料及应用该掺合料的混凝土，预拌高性能混凝土掺合料由如下重量份数的原料组成：粉煤灰40‑90份；改性橡胶粉8‑20份；木屑活性炭‑早强料5‑10份；聚合物70‑100份；改性橡胶粉为由橡胶粉经过硅烷偶联剂改性后，再经过耐低温材料包覆制成；木屑活性炭‑早强料为由木屑活性炭和早强剂制成。本发明设计并制备一种具有抗冲击能力的、延长服役年限的、具有耐久性的高性能混凝土掺合料，并将其应用于混凝土中，以获得一种具有抗冲击、长寿命的高性能混凝土。
