Polymer concrete composition containing atomized steel slag and method for producing the same

Abstract

Disclosed is a polymer concrete composition containing atomized steel slag and a manu¬ facturing method thereof. In the polymer concrete composition including an aggregate and a thermosetting resin for binding the aggregate, a fine and / or coarse aggregate of the aggregate are replaced with atomized steel slag which has a high solid volume and a high density and is spherical in shape, thereby enhancing fluidity of the polymer concrete composition, reducing the amount of the thermosetting resin and increasing the amount of the aggregate per unit volume, consequently increasing engineering properties of polymer concrete products including com¬ pressive strength and fluidity and generating economic benefits.

Description

technical field [0001] The present invention relates to a polymer concrete composition containing atomized steel slag and a method for producing the same, and more particularly to a polymer concrete composition containing atomized steel slag contained as an aggregate in a polymer concrete composition including a thermosetting resin In the material, the fluidity of the polymer concrete composition can be increased, and the shape of the atomized steel slag is almost spherical, so that the amount of thermosetting resin can be reduced, and finally economic benefits can be generated and the compression and compression of the concrete product can be increased. Flexural strength, and its method of manufacture. Background technique [0002] Generally, construction and engineering concrete mainly composed of cement, water and aggregate (further containing admixtures as required) is poured on site or applied in the following way: when precasting is required, the ratio of water to ceme...

AI Technical Summary

Problems solved by technology

However, this type of commonly used concrete has the following problems: the durability of the steel bar is weakened by corrosion, neutralization, damage by sea wind and water, etc.

In order to solve this phenomenon, the method of coating steel bars with chemical resins such as epoxy resins, urethanes, silicones, unsaturated polyesters, etc. or using paints is adopted, but its disadvantages are related to durability, economical benefits, and adhesion closely related

In particular, Portland cement concrete, which is a typical construction material, has advantages in terms of economic benefits and structural properties, but has the following disadvantages: slow hardening and reduced tensile strength due to the binder being cement hydrate , Increased drying shrinkage and deterioration of chemical corrosion resistance

However, the atomized steel slag has a higher density than other materials to cause material segregation, making it difficult to finally apply the atomized steel slag to fields other than concrete for special purposes

[0006] Korean Unexamined Patent Publication No. 10-2007-0095706 (Title: Ultra-light or ultra-high-weight polymer concrete composition having high strength, its preparation method, and method of manufacturing polymer concrete products using the method) discloses that the and steel slag crushed into a powder state as a powder material, atomized steel slag as a substitute for a part of the aggregate, and iron fibers and steel fibers to achieve extremely high weights to make polymer concrete compositions, but the resulting The strength of the product is unfavorably lower than that of commonly used polymer concrete
