Abstract

The invention relates to green vegetation ecological slope protection concrete and a preparation method thereof. The green vegetation ecological slope protection concrete is prepared from the following raw materials in parts by weight: 60-75 parts of aggregate, 30-40 parts of cement, 2-5 parts of a superplasticizer, 2-5 parts of superfine silicon dioxide, 2-5 parts of organic fibers, 0.5-2 part ofan early strength agent, 0.1-0.5 part of an expanding agent, 0.1-0.5 part of hydroxypropyl starch ether and 0.1-0.5 part of a mineral admixture. The aggregate is machine-made sand, the particle sizeof the machine-made sand is 20-60 meshes, and the machine-made sand comprises 20% of machine-made sand with the particle size of 20-30 meshes, 45% of machine-made sand with the particle size of 31-50meshes and 35% of machine-made sand with the particle size of 51-60 meshes. The green vegetation ecological slope protection concrete is low in cost, simple in construction process, low in maintenanceand management cost after construction and excellent in performance, has the advantages of no cracking, no shedding, no deformation and excellent high-strength construction performance, and effectively solves the problem of contradiction between slope protection safety protection building and natural environment protection.

Description

technical field [0001] The invention belongs to the technical field of building materials, in particular to a green vegetation ecological slope protection concrete and a preparation method thereof. Background technique [0002] With the rapid development of my country's economy, the construction of various highways is in full swing across the country. In the process, roadbed slope protection, as an important structure to ensure the stability of the roadbed, has also received more attention; and with the current green With the prevalence of development concepts, ecological slope protection technology has been widely used in highway engineering. The traditional ecological slope protection only planted some green vegetation on the roadbed slope without considering the stability of the roadbed slope, which is far from enough in coastal soft soil areas. [0003] Therefore, it is very important to seek a new type, green ecology, and high stability green vegetation ecological slope...
