Abstract

The invention relates to an imitated stone environment-friendly concrete road brick which comprises a surface layer and a base layer. The surface layer comprises, by weight, 5-30% of cement, 70-95% of at least one of quartz sand, granite broken sand and tailing sand and 5-30% of one of ethylene vinyl acetate, acrylic resin and waterborne epoxy resin, and the base layer comprises 3-10% of cement, 0-20% of mineral powder, 0-10% of coal ash, 10-50% of coal ash slag, 10-40% of iron ore dressing bits of 1.0-3.0% in fineness modulus and 35-50% of iron ore dressing bits of 2-10mm in grain diameter. The invention further relates to a making method of the road brick. The making method includes that an original producing, stirring and feeding sequence is adjusted, a binder is completely used to replace water for the surface layer, and a stirring process is improved specially. After a new material is used, feasibility of production links like stirring, material distributing, mould press-forming and demoulding is realized by technical means like changing feeding sequence and increasing stirring time. Compared with conventional surface layer mortar, the new surface layer is higher in flexibility and better in waterproofness, alkali efflorescence of cement products is inhibited, sand is protruding in texture, and the road brick has imitated stone effect integrally.

Description

technical field [0001] The invention belongs to the technical field of pavement brick manufacturing, in particular to a stone-like environment-friendly concrete pavement brick and a manufacturing method thereof. Background technique [0002] At present, cement is a traditional, cheap and reliable civil engineering material used in a very large amount, and there is no other material that can replace it for a long period of time. Therefore, cement is also a material with great vitality, but its related environmental and resource issues are also increasingly concerned by the state and society. [0003] The consumption of resources and energy in the process of cement production is large, causing serious environmental pollution. For example, cement production consumes a large amount of limestone resources and clay resources. In my country, 1.4t~1.5t limestone, 0.2~0.3t clay and 0.2t coal are used for each ton of cement clinker. At the same time, the production emits a large amo...
