Abstract

The invention discloses a preparation method of long-service-life colored pervious concrete, and belongs to the technical field of concrete. The method comprises the following steps: (1) weighing raw materials; (2) performing high-pressure homogenization treatment; (3) performing variable-speed stirring treatment; (4) performing cryogenic-ultrasonic coupling treatment; and (5) performing stirring treatment. According to the preparation method of the long-service-life colored pervious concrete, the technologies of high-pressure homogenization, variable-speed stirring, cryogenic-ultrasonic coupling treatment and the like are applied to processing and manufacturing of the concrete, so that the compression resistance and the water permeability of the concrete are remarkably improved, and experimental results show that the compressive strength and the permeability coefficient of the concrete prepared by the method are obviously superior to those of a control group, and the service life of the pervious concrete is more effectively prolonged.

Description

technical field [0001] The invention belongs to the technical field of concrete, and in particular relates to a color permeable concrete with high service life and a preparation method thereof. Background technique [0002] Permeable concrete is an important part of sponge city construction. At present, my country's urbanization level is developing rapidly, and in the process of urbanization, non-permeable cement concrete pavement has gradually replaced the original green vegetation, changing the natural soil vegetation and the natural permeable properties of the underlying layer. This change has brought about a series of ecological problems. In rainy weather, due to the existence of impermeable cement concrete, rainwater will accumulate on the surface to form surface runoff, and the water from surface runoff generally enters rivers through the urban drainage system. In lakes and seas, groundwater cannot be replenished. Since the "sponge city" policy was put forward, the r...
