Ecological concrete building block similar to sponge and preparation method thereof

Abstract

The invention provides an ecological concrete building block similar to a sponge. The ecological concrete building block similar to the sponge has multiple features of being high in water permeability, water retention and intensity, suitable for growth of animals and plants, capable of being self-locked and engaged and the like. The ecological concrete building block similar to the sponge is composed of a concrete frame with concave and convex grooves, a phenolic aldehyde water retention cushion layer, large aggregate non-fine concrete and composite nutrient soil. The concrete frame with the concave and convex grooves is filled with the large aggregate non-fine concrete; pores and the surface of the large aggregate non-fine concrete are filled with the composite nutrient soil; the phenolic aldehyde water retention cushion layer is laid at the bottom of the large aggregate non-fine concrete. The phenolic aldehyde water retention cushion layer at the bottom has the high water retention and high water permeability, can store water for need of growth of the plants when rain is small or water conservation is needed at ordinary times, and can be pervious to water rapidly when rainstorms happen or rain is large. The internally filled large aggregate non-fine concrete has good water permeability and air permeability, the communicated pores are suitable for rotting growth of the plants, and the ecological concrete building block can provide a multiply and habitat environment for aquatic animals when applied to the underwater.

Description

technical field [0001] The invention relates to a civil engineering material component, in particular to a sponge-like ecological concrete block and its manufacturing method, which is mainly suitable for slope protection bricks for bank slopes, sidewalks, squares, and roof greening in the fields of water conservancy, transportation, and municipal administration. , Taoban bricks, green bricks. Background technique [0002] At present, extreme weather occurs from time to time, sometimes with continuous high temperature and drought, and sometimes with continuous torrential rain, causing urban waterlogging, so the country proposes to build a sponge city. Some existing concrete blocks, bricks, etc., one is dense structure, high strength, but it is difficult to plant plants on it or the greening rate is very low, and the water permeability is poor, and the other hollow block can plant plants but the strength Poor and hard to hold water. Contents of the invention [0003] In or...
