Production process of high-strength concrete capable of being quickly coagulated

Abstract

The invention discloses a production process of high-strength concrete capable of being rapidly coagulated. The production process comprises the following steps: preparation of raw materials, preliminary mixing of aggregates, treatment of water, mixing of additives, modification of the aggregates, treatment of coarse aggregates, enhancement of the aggregates and transfer of the concrete. According to the production process of the high-strength concrete capable of being quickly coagulated, various high-strength fine aggregates are arranged, and by adding the silica fume, the glass fibers and the carbon nanofiber fine aggregates, the physical structure of the concrete can be effectively improved, and gaps among coarse aggregates such as gravel in the concrete are filled; wherein the silica fume has a higher surface volume ratio and a faster hardening reaction. The silica fume is used for improving the strength and durability of the concrete, so that the coarse aggregates are combined more tightly, the overall structural strength of the concrete is improved, and the concrete has better impact resistance and can adapt to various complex construction requirements.

Description

technical field [0001] The invention relates to the technical field of concrete, in particular to a high-strength and fast-setting concrete production process. Background technique [0002] Concrete is a composite material made by bonding fine and coarse aggregates with cement and hardening over a period of time. In the past, lime-based cements were most common, such as lime paste, but hydraulic cements are also sometimes used, such as Calcium aluminate cement or Portland cement. Non-cementitious concrete differs from other concretes in that it directly bonds various aggregates. Non-cement-based concrete includes asphalt concrete using asphalt bond and polymer concrete using polymer as cementitious material. Among them, asphalt concrete is often used in road surfaces. When the aggregate is mixed with dry Portland cement and water, the mixture forms a slurry that is easy to pour and shape. Cement reacts with water and other ingredients to form a hard matrix that holds thes...

Problems solved by technology

[0004] The purpose of the present invention is to provide a high-strength and fast-setting concrete production process to solve the above-mentioned background technology. The existing concrete on the market mostly uses sand and gravel as aggregates, which causes the strength of the concrete to be affected by the sand and gravel. Strength limitation, unable to meet the requirements of some high-strength construction conditions
