Ecological concrete

Abstract

The invention discloses ecological concrete which comprises 1,400-1,500Kg of aggregate, 150-300Kg of sand, 250Kg of cement, 5L of an additive and 67.5-110L of water, wherein the cement is P.gO 42.5-grade common Portland cement; the sand is natural river sand with the fineness modulus of 2.46 and the bulk density of 1,489kg / m<3>; the aggregate is obtained by processing natural stone, and the particle size of the aggregate is 5-16.5mm; the additive consists of the following materials in parts by weight: 5.10 parts of calcium carbonate, 40.50 parts of silicon powder, 5.8 parts of lignin sulfuric acid, 1.3 parts of an early strength agent, 0.3.0.4 part of a water retaining agent and 0.01.0.02 part of an air entraining agent; the early strength agent is sodium nitrite; a water reducing agent is a polycarboxylic ether high-efficiency water reducing agent; the water retaining agent is polyacrylamide; and the air entraining agent is sodium dodecyl benzene sulfonate. In the invention, through the permeability and water holding and purifying functions of permeable ecological concrete as well as the adaptability of plant-growing ecological concrete to the treatment of micro-polluted water (rainwater), the functions of rainwater collection and artificial wetland purification are realized.

Description

technical field [0001] The invention relates to an ecological concrete, in particular to an ecological concrete used in artificial wetlands. Background technique [0002] Ecological concrete refers to concrete materials that can adapt to the growth of animals and plants, regulate ecological balance, beautify the environment and landscape, and realize the coordination between human beings and nature. Ecological concrete can be divided into permeable ecological concrete and plant-growing ecological concrete. Among them, the permeable ecological concrete has the functions of water permeability and water purification, while the plant-growing ecological concrete is a kind of concrete that can grow plants and has protective functions. [0003] Because permeable ecological concrete has many excellent ecological characteristics as a pavement material, under the guidance of human beings seeking harmony with nature, maintaining ecological balance and sustainable development, some deve...

[0004] my country is a country with a relative shortage of resources, and water pollution is becoming more and more serious. On the other hand, rainwater is directly discharged and has not been fully utilized.

For a long time, my country has only paid attention to the flood control and drainage function of the rainwater drainage system, ignoring the huge value of rainwater resource use and governance utilization
