Abstract

The invention is used for mainly overcoming the deficiencies of low compressive strength and poor flexural strength of concrete, and provides a reinforced concrete preparation method with simple preparation process. Reinforced concrete has the advantages of light weight, high strength and high toughness and is expected to be directly applied to batch industrial production in future. The invention aims to provide the reinforced concrete including the following components in parts by weight: 11.98-12.80 parts of cement, 1.50-1.82 parts of fly ash, 1.1076-1.1143 parts of a mineral powder, 4.79-4.97 parts of water, 22.29-22.45 parts of sand, 30.9-31.9 parts of stone, and 0.368-1.389 parts of a carbon fiber composite material. The carbon fiber composite material includes epoxy resin and a carbon fiber, wherein the weight of the epoxy resin accounts for 30%-33% of the weight of the carbon fiber composite material.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to reinforced concrete and a preparation method. Background technique [0002] With the continuous development of modern construction technology, higher requirements are put forward for cement concrete, which is developing in the direction of high strength, high toughness, high crack resistance, high durability, high volume stability and excellent manufacturability. However, concrete is prone to cracks during use, especially under the condition of tensile stress, which eventually leads to complete destruction of materials and structures. Therefore, the strengthening and toughening of concrete has been an interdisciplinary problem that has been devoted to research in the fields of mechanics and materials science for many years. The research and application of steel fiber reinforced concrete are the most mature at home and abroad. However, studies have shown that steel ...
