High-strength and high-toughness pervious cement concrete and preparation method thereof
The invention discloses high-strength and high-toughness pervious cement concrete and a preparation method thereof, and belongs to the field of concrete materials. Starting from the formation mechanism of the mechanical properties of the pervious cement concrete, the calcium carbonate whiskers with high strength and high elasticity modulus are introduced as a microscopic reinforcing material, andan inorganic gelling agent is used as an auxiliary material, so that the improvement effect of the calcium carbonate whiskers on the strength, toughness and bonding capacity of the pervious cement concrete gelling material is improved; meanwhile, the ultra-short cut polyethylene fiber is introduced as a macroscopic reinforcing material, so that the crack resistance and the deformation capacity ofthe cementing material are further improved, the high-strength and high-toughness water-permeable cement concrete material is invented, and the technical problem of poor toughness of pervious cement concrete is fundamentally solved; and the pervious cement concrete material is balanced and unified in the aspects of high strength and high toughness.
本发明公开了一种高强高韧的透水水泥混凝土及其制备方法，属于混凝土材料领域。本发明从透水水泥混凝土力学性能的形成机制出发，通过引入高强度、高弹性模量的碳酸钙晶须作为微观增强材料，辅以无机胶凝剂，提高其对透水水泥混凝土胶凝材料强度、韧性和粘结能力的改善效果；同时，引入超短切聚乙烯纤维作为宏观增强材料，进一步提高胶凝材料自身的抗裂能力和变形能力，从而发明了一种高强高韧的透水水泥混凝土材料，从根本上解决了透水水泥混凝土韧性差这一技术难题，使透水水泥混凝土材料在高强度和高韧性方面实现了平衡与统一。
