Abstract

The invention belongs to the technical field of sound barrier materials, and particularly relates to a cement-based sound-absorbing and water-permeable sand plate and a manufacturing method thereof. The sand plate comprises a bottom layer and a surface layer, and raw materials of the sand plate comprise quartz sand, white cement, rubber powder, 108 glue, a polycarboxylate superplasticizer, cellulose ether, an early strength agent, a retarder and pigment; the manufacturing method of the sand plate comprises the following steps: S1, preparing raw materials; S2, forming a green body; and S3, performing drying. The manufactured sand plate has uniform through gaps, good water permeability is achieved, the compactness is high, the compressive strength and breaking strength of the plate are veryhigh, and the national standard is met.

Description

technical field [0001] The invention belongs to the technical field of sound barrier materials, and in particular relates to a cement-based sound-absorbing and water-permeable sand board and a manufacturing method thereof. Background technique [0002] In the process of long-term urbanization in my country, large-scale impermeable ground has replaced the original forests, green spaces, and fields, resulting in a large increase in impermeable area, preventing urban rainwater from entering the soil smoothly, resulting in a large reduction in groundwater replenishment and conservation, and flood peak flow. greatly increase. In many cities, when there is a heavy rain, the rainwater on the road surface cannot seep quickly. When the drainage facilities are not smooth, it is easy to cause urban waterlogging. At the same time, ground hardening weakens the breathing function of the urban environment, causing heat island effects, dust and noise pollution to intensify, deteriorating th...
