Low-alkalinity cementing material for vegetation concrete as well as preparation method and application of low-alkalinity cementing material
The invention provides a low-alkalinity cementing material for vegetation concrete as well as a preparation method and application of the low-alkalinity cementing material. The low-alkalinity cementing material for the vegetation concrete comprises the following components in parts by weight: 30-60 parts of sulphoaluminate cement, 30-60 parts of a mineral admixture, 5-30 parts of gypsum, 2-8 parts of an alkali eliminating agent, 2-10 parts of an alkali sealing agent and 2-10 parts of a coagulant, the alkali sealing agent can directly form a film in a matrix to achieve an alkali sealing effect, can realize alkali sealing balance, and can realize the effect of simultaneously sealing alkali in the early stage and the later stage of the matrix; the 2-ethylhexanoic acid-3-alkoxy-2-hydroxy propyl ester is added into the alkali sealing agent, so that the alkali sealing effect is improved, and the service life of the alkali sealing agent is prolonged. The 2-ethylhexanoic acid-3-alkoxy-2-hydroxy propyl ester is crosslinked with the styrene-acrylic emulsion and the rubber powder to form a compact crosslinked compound, the internal stress of the film during curing shrinkage is relieved, the hydrophilicity of the film can be reduced, and the falling of the film layer caused by rain wash is prevented.
本发明提供了一种植生混凝土用低碱度胶凝材料及其制备方法和应用，所述植生混凝土用低碱度胶凝材料包括以重量份计的如下组分：硫铝酸盐水泥30‑60份、矿物掺合料30‑60份、石膏5‑30份、消碱剂2‑8份、封碱剂2‑10份和促凝剂2‑10份；所述封碱剂能在基体内部直接成膜，达到封碱的效果，并能够实现封碱的平衡，可以实现对基体前期和后期同时封碱的效果，通过在封碱剂中加入2‑乙基己酸‑3‑烷氧‑2‑羟基丙酯，2‑乙基己酸‑3‑烷氧‑2‑羟基丙酯与苯丙乳液和胶粉发生交联，形成致密的交联化合物，并缓解膜固化收缩时的内应力，能降低其亲水性，并防止由于雨水冲刷导致膜层的脱落。
