Abstract

The invention discloses cement concrete, which has the advantages of fine particle, good fluidity, low hydration heat, low shrink, small water demand, high early strength and the like. Moreover, the alkalinity is low and the alkali-aggregate reaction of the cement concrete is inhibited; the compactness is high and the durability of the concrete is increased; the concrete interface surface and the gaps of gelled materials can be fully filled, the interface structure of the concrete is improved, the compressive property , the tensile property and the like are improved, the early cracks of the pumped concrete are effectively reduced, the later-stage desiccation is compensated, the crack resistance is improved, and the construction cost and the maintenance expense are reduced, i.e. the production cost is reduced; and the insolation resistance is high, the cement concrete is not apt to conduct heat, the external structure can be changed easily, the mechanism strength is good, the heat resistance, the compression resistance, the impact resistance and the humidity resistance are high, no condensation is caused because of cold and hot alternation, and the cement concrete can adopt to all kinds of climatic conditions.

Description

technical field [0001] The invention relates to a cement concrete for building construction. Background technique [0002] Concrete is a mixture of cement (usually Portland cement) and aggregate. When a certain amount of water is added, the cement hydrates to form a microscopic opaque lattice structure that wraps and binds the aggregate to form an overall structure. Usually concrete structures have strong compressive strength (about 35MPa). However, the tensile strength of concrete is low, usually only about one-tenth of the compressive strength, and any significant tensile bending action will cause its microscopic lattice structure to crack and separate, resulting in structural damage. However, most structural members have the requirement of tensile stress inside, so unreinforced concrete is seldom used alone in engineering. Compared with concrete, the tensile strength of steel bars is very high, generally above 200MPa. Therefore, people usually add reinforcing materials ...
