引用本文摘 ? 要：測試了閃長玢巖的吸水特性，研究了閃長玢巖作為粗骨料對混凝土施工性能的影響。結果表明：閃長玢巖碎石內部的裂隙、孔隙較發達，吸水率高，但吸水速率慢；閃長玢巖的摻入使得混凝土拌合物的流動性損失顯著增加，泌水率降低；采用骨料預濕工藝和摻減水劑的方法可以解決閃長玢巖混凝土的施工性能問題。 Abstract: The water absorption characteristics of diorite porphyrite was tested, and its influence on the construction performance of concrete was studied. The results show that the fissures and pores in the diorite porphyrite are relatively developed, and the water absorption is high, but the water absorption rate is slow. The addition of diorite porphyrite significantly increases the fluidity loss of concrete mixture and reduces the bleeding rate. The problem of construction performance of diorite porphyrite concrete can be solved by using aggregate pre-wetting technology and adding water reducing agent.
