Abstract
The invention relates to the technical field of photocatalytic cement-based materials and provides a preparation method of a photocatalytic cement-based material. The preparation method comprises thefollowing steps of firstly, preparing a cement matrix layer; secondly, preparing a photocatalytic covering layer, and then coating the surface of the cement matrix layer with the photocatalytic covering layer to obtain a photocatalytic cement complex; and finally, putting the photocatalytic cement complex in water for maintenance. In the preparation method, a cement sample in the photocatalytic covering layer is identical to a cement sample in the cement matrix layer, so that the two of the photocatalytic covering layer and the cement matrix layer are easier in crystallization combination, i.e. the structure stability of the photocatalytic cement complex is higher; by putting the photocatalytic cement complex in the water for still standing, the combination rate of a cement sample crystalin the photocatalytic covering layer and a cement sample crystal in the cement matrix layer can be accelerated, and the compressive strength of the photocatalytic cement complex is further improved; and the whole process is simple to operate without using an additional adhesive and lower in cost and is more environmentally friendly.
