Non-sparking concrete and preparation method thereof
The invention discloses misfire concrete and a preparation method thereof. The misfire concrete is prepared from the following components in parts by weight: 240 to 310 parts of cement, 42 to 48 parts of fly ash, 28 to 32 parts of phosphorus slag powder, 1180 to 1270 parts of selected dolomite sand, 670 to 690 parts of selected dolomite gravel, 190 to 200 parts of water and 10.56 to 13.11 parts of additive. A large amount of industrial solid wastes including the selected dolomite sand, the selected dolomite gravels, the fly ash and the phosphorus slag powder are utilized, the weight ratio of the solid wastes is about 80%, the selected dolomite gravels and the cementing material are effectively combined by adjusting the dosage of each component, the solid waste resources are comprehensively utilized, the workability of the concrete is good, and the service life of the concrete is prolonged. The mechanical property meets the standard requirement, the concrete does not generate sparks and sparks after being subjected to metal polishing, impacting and chopping, fire-fighting potential safety hazards can be effectively avoided from materials, the fire-fighting and explosion-proof requirements are met, and the concrete is suitable for being popularized and used in special projects with the fire-fighting and explosion-proof requirements.
本发明公开了一种不发火混凝土及其制备方法，所述不发火混凝土包括以下重量份的组分：水泥240～310份，粉煤灰42～48份，磷渣粉28～32份，采选白云石砂1180～1270份，采选白云石碎石670～690份，水190～200份，外加剂10.56～13.11份。本发明大量地利用工业固体废弃物，包括采选白云石砂、采选白云碎石、粉煤灰和磷渣粉，固体废弃物重量占比80％左右，通过对各组分的用量调整，有效将采选白云砂石与胶凝材料结合起来，固废资源综合利用，不仅混凝土的和易性良好，力学性能满足规范要求，且混凝土经金属打磨、撞击、劈砍，不产生火星和火花，从材质和材料上能够有效避免消防安全隐患，满足防火防爆的消防要求，适宜在具有消防防爆要求的特殊工程中推广使用。
