Basic magnesium sulfate cement concrete and preparation method thereof
The invention discloses basic magnesium sulfate cement concrete. The basic magnesium sulfate cement concrete is prepared from the following components in parts by mass: 300-400 parts of basic magnesium sulfate cement; 900-1150 parts of coarse aggregate; 650-750 parts of fine aggregate; 80-200 parts of filler; the filler comprises porous particles, pores of the porous particles are filled with degradable components, and the degradable components comprise degradable resin and an oxidizing agent used for accelerating degradation of the resin according to the mass ratio of 10: 1. The porous particles are added into the concrete, the degradable resin is added into the pores of the porous particles, and after the degradable resin is degraded in the pores of the porous particles, cavities are formed in the porous particles, so that a certain expansion space is provided for cement in the later period, and the possibility of concrete cracking is reduced.
本发明公开了一种碱式硫酸镁水泥混凝土，述碱式硫酸镁水泥混凝土由包括以下质量份数的组分制备而成：碱式硫酸镁水泥300‑400份；粗骨料900‑1150份；细骨料650‑750份；填料80‑200份；所述填料包括多孔颗粒，所述多孔颗粒的孔隙内填充有可降解组分,所述可降解组分包括质量比例为10：1的降解树脂和用于加速树脂降解的氧化剂。通过在混凝土内添加有多孔颗粒，并在多孔颗粒的孔隙内添加降解树脂，当降解树脂在多孔颗粒的孔隙内降解后，会使多孔颗粒内呈现有空腔，从而提供给水泥在后期一定的膨胀空间，减小了混凝土破裂的可能性。
