Embodiment 1

[0042] The spongy concrete brick of the present invention is made of concrete including garden waste, wherein the concrete used includes the following types:

[0043] (1) The spongy garden waste concrete of the present invention includes cement, sand, stones, and garden waste. The garden waste is fragmented garden waste after crushing; the concrete is made by uniformly mixing cement, sand, stones, fragmented garden waste and water, and its weight ratio is: cement: sand: The weight ratio of stone: fragmented garden waste: water is 100:90:190:5:45. Among them, the cement is 42.5 ordinary Portland cement; the sand is medium-coarse sand; the particle size of the stone is 5mm-25mm.

[0044] The preparation method comprises the following steps: step 1: drying garden wastes to obtain product 1; step 2: pulverizing the product 1 to obtain product 2 with a particle diameter of 0.1-3 cm; step 3: passing product 2 through a 10-mesh sieve Screening to obtain fragmented garden waste; Ste...

Embodiment 2

[0103] In order to further promote urban greening construction and beautify the urban landscape, the sponge concrete brick in the first embodiment can be structurally improved to be suitable for planting plants. Ordinary concrete bricks are generally elongated bricks, that is, slab bricks, and in this embodiment, such as figure 1 As shown, one side of the concrete brick is slope 1, from the section perpendicular to slope 1 (see figure 2 ), the profile of the concrete brick is trapezoidal or similar, and there are holes 2 on the slope 1. The number of holes can be 1-10, and they are evenly distributed in the length direction. In this embodiment, the holes 2 pass through the bottom surface 3. In other embodiments, the hole can pass through the opposite side of the slope 1, or pass through the side and the bottom 3 at the same time, or not pass through any other surface to form an inner cavity inside the concrete brick. The holes 2 can be circular or other shapes, which can be ...

Abstract

The invention discloses a sponge concrete brick and application thereof. The concrete brick is prepared from concrete; the concrete disclosed by the invention comprises cement, sand, garden waste, regenerated stones and a brightener at the weight proportion of 100 to (100-140) to (200-290) to (5-35) to (0.15-1.15). According to the sponge concrete brick, optimal configuration of renewable resources of the garden waste material in an urban construction process is achieved by the garden waste. The concrete brick disclosed by the invention has the advantages of relatively good water absorptivity, water permeability and air permeability, relatively high strength, available raw materials, and low preparation cost; and green plants are easy to plant.

Description

technical field [0001] The invention relates to the field of construction, in particular to a sponge concrete brick and its application. Background technique [0002] With the continuous prosperity and development of the world economy, the earth has gradually changed its original appearance. Urban construction is changing with each passing day and developing rapidly, and at the same time, people are surrounded by the world of reinforced concrete. Public buildings, residences, and road construction harden the surface environment, almost completely changing the ecological environment of the construction site, and the atmospheric evaporation cycle is affected, resulting in a decrease in air humidity and an increase in temperature in the urban area, forming a "heat island effect", and greening such as urban green spaces This phenomenon is also exacerbated by the absence of This "heat island effect" makes the city hotter and hotter in summer, and the dust in the atmosphere incr...
