Problems solved by technology

[0004] In view of the above-mentioned related technologies, the inventor believes that in the actual application process of the above-mentioned C30 concrete, because the bonding force between the recycled aggregate and the cementitious material is lower than that of the original aggregate, and the recycled aggregate is prone to cracks and gaps in the process of processing , so the crack resistance of the prepared concrete is not up to the standard

Abstract

The invention relates to the technical field of concrete preparation, and particularly discloses C30 concrete and a preparation method thereof. The C30 concrete is prepared from the following components: cement, fly ash, sand, gravel, water, a water reducing agent, kenaf fibers, a bamboo pulp lignin dispersing agent and rubber powder, wherein the kenaf fibers are subjected to modification treatment; the preparation method comprises the following steps: S1, mixing the cement, the fly ash, the sand, the gravel, the kenaf fiber, the bamboo pulp lignin dispersant, the rubber powder and the water, and stirring for 40-60 seconds to obtain a mixture; and S2, adding water and a water reducing agent into the mixture, and stirring for 60-90 seconds to obtain the C30 concrete. The C30 concrete has the advantage that the anti-cracking performance of the concrete can be enhanced.

Description

Technical field [0001] The present application relates to the field of concrete preparation techniques, and more particularly, it relates to a C30 concrete and its preparation method thereof. Background technique [0002] Ordinary concrete refers to cement as the main gelation material, with water, sand, stone, and necessary to incorporate chemical extension and mineral blending, in accordance with appropriate proportion, with uniform mixing, dense molding, and hardened artificial stone materials . Concrete strength is the most important indicator in the performance of concrete. The concrete strength grade is divided by cubic compressive strength standard value, and the general concrete strength grade is divided into 14th: C15, C20, C45, C50, C55, C60, C65, C70, C75, and C80. [0003] In the relevant technique, as the application number is shown in 201710322578.2, a C30 concrete is disclosed. Each cubic C30 concrete consists of a raw material containing the following weight: ceme...
