Preparation process of anti-crack mass concrete applied to road engineering construction
The invention discloses a preparation process of anti-crack mass concrete applied to road engineering construction, and the anti-crack mass concrete applied to road engineering construction is characterized by being prepared from the following components in parts by mass: 240 to 290 parts of cement, 120 to 145 parts of water, 40 to 70 parts of mineral powder, 35 to 65 parts of fly ash, 20 to 40 parts of silica powder, 820 to 950 parts of gravel, 480 to 580 parts of sand and 7 to 14 parts of pumping agent. According to the preparation process of the anti-crack mass concrete applied to road engineering construction, the mineral admixture is adopted, and the specific gravity of the concrete is specifically optimized, so that the later strength and durability of the concrete are reasonably and effectively enhanced, and meanwhile, the cement consumption is reduced; according to the present invention, the production cost is reduced, the cement hydration heat release rate and the occurrence rate of the concrete crack are reduced, and the anti-cracking agent, the pumping agent, the anti-cracking fiber and the shrinkage reducing additive mixed with the basic raw materials can effectively inhibit the generation of the concrete crack together.
本发明公开了一种应用于道路工程建设的抗裂大体积混凝土制备工艺，所述一种应用于道路工程建设的抗裂大体积混凝土，其特征在于，由以下质量份数的组分制备而成：水泥240～290份、水120～145份、矿粉40～70份、粉煤灰35～65份、硅微粉20～40份、碎石820‑950份、砂480～580份、泵送剂7～14份。该应用于道路工程建设的抗裂大体积混凝土制备工艺，通过除采用矿物掺合料外，还将具体优化其自身比重，在合理、有效的增强混凝土的后期强度及耐久性的同时减少水泥用量，降低生产成本且降低水泥水化热的释放速度和混凝土的裂缝的发生率，与此同时，与基本原料混合的抗裂剂、泵送剂、防裂纤维、减缩外加剂可共同有效的抑制混凝土的裂缝的产生。
