Modified calcium oxide expanding agent for compensating concrete temperature shrinkage and preparation method thereof
The invention provides a modified calcium oxide expanding agent for compensating concrete temperature shrinkage and a preparation method thereof. The modified calcium oxide expanding agent for compensating concrete temperature shrinkage is composed of a core layer and a wrapping layer, wherein the core layer is made of an expanding material, and the wrapping layer is made of a phase-change material; and the weight of the phase-change material accounts for 6-10% of the total weight of the expanding agent. The modified calcium oxide expanding agent provided by the invention has the characteristics such as simple preparation technology, wide-source and cheap and easily-available raw materials and good compensation effect on concrete temperature shrinkage, is suitable for compensating large-volume concrete temperature shrinkage and is of remarkable social and economic significance.
