Abstract

The invention discloses a composite lightweight aggregate ecological cement concrete floating bed. The composite lightweight aggregate ecological cement concrete floating bed is prepared from, by weight, 20-30 parts of pumice stones, 2-5 parts of EPS polyphenyl granules, 20-30 parts of cement, 9-16.5 parts of water, 0.2-0.3 part of water reducer and 0.1-0.2 part of thickening time control agent, wherein the particle size of the pumice stones ranges from 26.50 mm to 31.50 mm, and the diameter size of the EPS polyphenyl granules ranges from 20.00 mm to 30.00 mm. Vegetation holes formed after logs are taken out can achieve a fixing effect on aquatic plant seedlings, and the root systems of aquatic plants can more easily make contact with water; the porosity of the concrete floating bed is large, and sufficient space can be provided for growth of the plant root systems; the pumice stones and the EPS polyphenyl granules are compounded, the density of the floating bed is reduced, and floating is achieved; by means of the porous adsorption capacity of cement hydration products and the pumice stones, an adsorption effect is generated on nutritional ingredients in a eutrophic water body, then nutrients are provided for the aquatic plants rooting in the floating bed, nutrients can be provided for the aquatic plants dually through the floating bed and the eutrophic water body, and a good effect is achieved for improving the purification capacity of the eutrophic water body.

Description

technical field [0001] The invention relates to the technical field of floating bed preparation, in particular to a composite lightweight aggregate ecological cement concrete floating bed and a preparation method thereof. Background technique [0002] Composite lightweight aggregate ecological cement concrete floating bed: it is a lightweight concrete floating bed made of pumice stone and EPS polyphenylene particles as composite aggregate and sulphoaluminate special cement as cementitious material. The floating bed can float on water and can carry plants of a certain quality. Both the plants and the pumice in the aggregate of the floating bed can purify nutrient-rich water. Pumice: It is a porous, light glassy acidic volcanic extrusive rock, the main components are silica and alumina, and the bulk density is 300.00Kg / m 3 , the porosity is 7l.80-81.00%, and the water absorption is 50.00-60.00%. EPS polystyrene particles: white spherical particles, the main component is furf...
