Cement-free low-carbon concrete and preparation method thereof
The invention provides cement-free low-carbon concrete completely replacing slag with coal gasification coarse slag and a preparation method of the cement-free low-carbon concrete. The cement-free low-carbon concrete is prepared from the following raw materials in parts by weight: 15-25 parts of a cementing material, 30-40 parts of fine aggregate, 35-48 parts of coarse aggregate, 3-8 parts of water and 0.04-0.03 part of a water reducing agent, wherein the cementing material comprises the following components in parts by weight: 20-60 parts of coal gasification coarse slag, 30-50 parts of steel slag, 10-30 parts of gypsum and 0-15 parts of lime kiln dust collection ash. The coal gasification coarse slag with low cost is used for completely replacing slag, cement is not used, the carbon emission of the concrete is reduced, and meanwhile, a corresponding concrete preparation method is provided for a concrete prefabricated part with medium and low strength.
本发明提供了一种利用煤气化粗渣完全代替矿渣的无水泥低碳混凝土及其制备方法，按重量份数计包括以下原料：胶凝材料15～25份、细骨料30～40份、粗骨料35～48份、水3～8份和减水剂0.04～0.03份；其中，所述胶凝材料按重量份数计包括：煤气化粗渣20～60份，钢渣30～50份，石膏10～30份，石灰窑收尘灰0～15份。本申请利用成本较低的煤气化粗渣完全代替矿渣，不使用水泥，降低混凝土的碳排放量的同时，为中低强度的混凝土预制件提供相应的混凝土制备方法。
