Glass fiber-reinforced vegetation form porous concrete and construction method thereof

Abstract

The invention discloses a glass fiber-reinforced vegetation form porous concrete and a construction method thereof. The construction method comprises the following steps: (1) uniformly mixing cement,water, an admixture and an aid, and preparing cement paste; (2) blending and stirring wetted coarse aggregates with the cement paste prepared in the step (1), so as to obtain coarse aggregates with the surfaces packaged with the cement paste; (3) pouring the coarse aggregates obtained in the step (2), simultaneously jetting chopped glass fibers to the surfaces of the coarse aggregates to adhere the glass fibers into the cement paste on the surfaces of the coarse aggregates, enabling the glass fibers and the coarse aggregates to simultaneously fall into a mold, and carrying out compaction and maintenance, so as to obtain the glass fiber-reinforced vegetation form porous concrete. By utilizing the construction method provided by the invention, the glass fibers with relatively high adding quantity can be added; by virtue of the jetted glass fibers, the situation that the cement paste on the surfaces of the coarse aggregates runs off downwards to block communication holes of the concrete is avoided; and the compressive strength and breaking strength of pervious concrete are remarkably improved, so that the pervious concrete is unlikely to be broken.

Description

technical field [0001] The invention relates to a planting type porous concrete and a construction method thereof, in particular to a glass fiber reinforced planting type porous concrete and a construction method thereof. Background technique [0002] Porous plant-planted concrete can be formed by mixing single-grain coarse aggregate with cement slurry. The concrete is composed of large aggregates wrapped in cement slurry to form a skeleton, with continuous pores in between, and nutrients can be poured into the pores. Add water-retaining materials into the pores as needed, then cover the concrete with soil, and sow plants adapted to the local climate and concrete pore environment. It can be used for strengthening and greening the slopes on both sides of roads and railways, embankment revetments, planted parking lots, planted sidewalks, planted roofs, green balconies, and even green ecological walls. [0003] The contact area between the coarse aggregates of planting concre...

AI Technical Summary

Problems solved by technology

Due to the small diameter of glass fiber and large water absorption, this process significantly reduces the fluidity of cement slurry, making it difficult for fiber cement slurry to wrap aggregate, so only a very small amount of fiber can be used, and the glass fiber is in the process of mixing. Bending will occur, reducing the reinforcement efficiency of the fibers
