Application of early strength concrete in prefabricating mortise and tenon member
The invention discloses application of early strength concrete in prefabricating a mortise and tenon member, and the early strength concrete comprises the following components: Portland cement, blast furnace slag, coal fiber stone, high-calcium fly ash, low-calcium fly ash, rice hull ash, natural volcanic ash, metakaolin and water. Portland cement, blast furnace slag, coal fiber stone, high-calcium fly ash, low-calcium fly ash, rice hull ash, natural volcanic ash and metakaolin are mixed in proportion for use, a proper amount of water is added, and the blast furnace slag and the coal fiber stone serve as aggregate; portland cement, high-calcium fly ash, low-calcium fly ash, natural volcanic ash and metakaolin are excited to react in an alkaline environment provided by rice hull ash to generate water-hardened gel, so that coagulation is realized, the strength of concrete is improved, the coagulation time of the concrete is shortened, and the early strength concrete with excellent performance is formed, so that the demolding time of a prefabricated member is shortened, and the purposes of increasing the mold turnover rate, improving the production efficiency and the factory efficiency of the prefabricated part and accelerating the structure construction are achieved.
本发明公开了早强混凝土在预制卯榫构件中的用途，早强混凝土成分为硅酸盐水泥、高炉矿渣、煤纤石、高钙粉煤灰、低钙粉煤灰、稻壳灰、天然火山灰、偏高岭土和水，将硅酸盐水泥、高炉矿渣、煤纤石、高钙粉煤灰、低钙粉煤灰、稻壳灰、天然火山灰和偏高岭土按比例混合使用，并添加适量的水，高炉矿渣和煤纤石作为骨料，硅酸盐水泥、高钙粉煤灰、低钙粉煤灰、天然火山灰和偏高岭土在因稻壳灰提供的碱性环境下激发发生反应生成水硬化凝胶，实现凝结，提高混凝土早其强度，缩短混凝土凝结时间，形成性能优异的早强混凝土，以缩短预制构件的脱模时间，达到加快模具周转率，提高生产效率和预制构件的出厂效率，加快结构施工的目的。
