The invention discloses a spraying type concrete accelerator, and belongs to the technical field of building materials. The accelerator is prepared from activated sepiolite, polyethyleneimine, modified nano graphene oxide and water, and in the preparation process, the components are weighed according to the raw material composition, the activated sepiolite, the polyethyleneimine, the modified nano graphene oxide and the water are added into a high-pressure reaction kettle, carbon dioxide gas is continuously introduced into the reaction kettle, after the pressure in the reaction kettle is increased to 0.6-0.8 MPa, stopping introducing, standing, when the pressure in the reaction kettle is reduced to 0.3-0.5 MPa, opening the reaction kettle, releasing the pressure to normal pressure, and discharging to obtain the spraying type concrete accelerator. The obtained spraying type concrete accelerator obtained has excellent later strength and durability.
本发明公开了一种喷射型混凝土速凝剂，属于建筑材料技术领域。本发明研制的速凝剂包括活化海泡石、聚乙烯亚胺、改性纳米氧化石墨烯和水组成，在配制过程中，先按原料组成称量各组分，将活化海泡石、聚乙烯亚胺和改性纳米氧化石墨烯和水加入高压反应釜，再向反应釜中持续通入二氧化碳气体，待压力上升至0.6～0.8MPa后停止通入，静置，待反应釜中压力降低至0.3～0.5MPa时，开启反应釜，泄压至常压，出料，即得喷射型混凝土速凝剂。本发明所得喷射型混凝土速凝剂具有优异的后期强度和耐久性。
