Modified calcium oxide expansion agent for cement concrete and preparation method of modified calcium oxide expansion agent
The invention provides a modified calcium oxide expansion agent for cement concrete. The modified calcium oxide expansion agent for the cement concrete has the specific surface area of 100-600m<2>/kg and is prepared from a degradable high polymer and calcium oxide expansion clinker. According to the modified calcium oxide expansion agent for the cement concrete, provided by the invention, the invalid hydration of calcium oxide at a plastic stage of concrete is reduced, the hardened expansion quantity is increased, and the shelf life of the product can be further prolonged; the expansion agent can be applied to the crack resisting and seepage prevention of a concrete structure and can be used for greatly improving the durability of the concrete.
