Abstract

The invention discloses an enhanced polymer concrete, which is prepared from the following raw materials in parts by weight: 5 to 25 parts of polymer, 0.1 to 1 part of wood fiber, 0.2 to 3 parts of polypropylene fiber, 0.1 to 5 parts of carbon fiber, 0.1 to 2 parts of stainless steel fiber, 0.1 to 2 parts of additive, 0.5 to 2 parts of cement, 30 to 60 parts of fine sand, 5 to 20 parts of broken stone, and a proper amount of water. In the prepared enhanced polymer concrete, the added fibers can form a network structure, and thus the concrete strength is strengthened. Furthermore, the added polymer can fill the pores in the concrete, thus the compactness of concrete is increased, and the concrete strength is further strengthened. The experiment results show that the prepared enhanced polymer concrete has good tensile strength and flexural strength, also has a compact structure, and can meet the engineering requirements.

Description

technical field [0001] The invention relates to the field of concrete materials, in particular to a reinforced polymer concrete and a non-impregnation preparation method thereof. Background technique [0002] Concrete is an artificial building material with certain strength characteristics composed of cementitious materials, aggregates and other fillers. Concrete has become an indispensable building material in civil engineering because of its wide applicability and low cost. With the increasing use of concrete, its performance has gradually been valued. Ordinary concrete, due to its poor tensile strength, high brittleness, poor crack resistance and poor ductility, limits its application. Polymer concrete, by adding polymers, polymers are filled in the internal pores of concrete, which can improve the deficiencies of ordinary concrete, improve the compactness of concrete, and increase the bonding force between cement stone and concrete. The preparation methods of polymer c...
