Non-sparking concrete and preparation method thereof
The invention relates to the field of concrete, and discloses misfire concrete and a preparation method thereof. The unfired concrete comprises the following raw materials: water, cement, unfired coarse aggregate, unfired fine aggregate, a flexibilizer, a refractory composition, an early strength water reducer and an air entraining agent, wherein the refractory composition is obtained by mixing calcined modified glass beads, epoxy resin and coke. The misfire concrete is prepared by the following steps: melting epoxy resin, adding calcined modified glass beads, and uniformly mixing with coke to obtain a refractory composition; and uniformly mixing the cement, the misfire coarse aggregate, the misfire fine aggregate, the refractory composition, the flexibilizer, the early strength water reducer and the air entraining agent, adding water while stirring, and uniformly stirring to obtain the fire-resistant concrete. The misfire concrete not only has good misfire performance, but also reduces the possibility that the antistatic capacity is reduced due to cracks generated by the misfire concrete.
本申请涉及混凝土领域，公开了不发火混凝土及其制备方法。不发火混凝土的原料包括水、水泥、不发火粗骨料、不发火细骨料、增韧剂、耐火组合物、早强减水剂和引气剂，耐火组合物是煅烧改性玻璃微珠、环氧树脂和焦炭混合得到。此不发火混凝土将环氧树脂熔融后，加入煅烧改性玻璃微珠、和焦炭混合均匀得到耐火组合物；然后将水泥、不发火粗骨料、不发火细骨料、耐火组合物、增韧剂、早强减水剂和引气剂混合均匀后，边搅拌边加水，搅拌均匀制得。本申请的不发火混凝土不仅具有较好的不发火性能，同时降低不发火混凝土产生裂缝而导致抗静电能力降低的可能。
