Aggregate concrete preparation process
The invention discloses an aggregate concrete preparation process, and relates to the field of concrete.The aggregate concrete preparation process comprises the following steps that 1, raw materials are prepared, specifically, 30-50 parts by weight of cement, 40-50 parts by weight of modified concrete aggregate, 10-12 parts by weight of a water reducing agent, 40-80 parts by weight of water, 30-40 parts by weight of fly ash, 10-20 parts by weight of slag powder, 10-15 parts by weight of polytetrafluoroethylene fibers and 10-15 parts by weight of silica fume are prepared, according to the invention, the modifier added with the carbon fiber is used for strengthening the concrete aggregate, so that the mechanical property of the aggregate is greatly improved, and when the modifier is added into concrete preparation, the stability of finished concrete is greatly improved; the durability of the finished concrete is further improved under the combined action of the added silica fume and the modified concrete aggregate, and finally, the high-temperature resistance of the concrete is greatly improved through polytetrafluoroethylene fibers uniformly mixed in the concrete, so that the whole concrete has a relatively long service life.
本发明公开了一种骨料混凝土制备工艺，涉及混凝土领域，包括以下步骤：步骤一：原料准备，准备相应重量份的水泥30～50份、改性混凝土骨料40～50份、减水剂10～12份、水40～80份、粉煤灰30～40份、矿渣粉10～20份、聚四氟乙烯纤维10～15份、微硅粉10～15份，本发明通过利用添加有碳纤维的改性剂对混凝土骨料进行强化，使得骨料的力学性能大大提高，使得在添加进入到混凝土制备中时，使得成品混凝土的稳固性大大提高，而加入的微硅粉与改性混凝土骨料共同作用使得成品混凝土的耐久性能进一步提高，最后通过均匀混入在混凝土中的聚四氟乙烯纤维，使得混凝土的耐高温性能大大提高，从而使得整体的混凝土具有较长的使用寿命。
