Embodiment 1

[0042] The embodiment of the present invention provides a kind of preparation method of novel pavement permeable concrete product, and preparation method comprises the following steps:

[0043] 1) Weigh 700kg of ordinary aggregate, 300kg of waste rubber aggregate, 320kg of Portland cement, 65kg of fly ash, 65kg of mineral powder, 12kg of composite admixture, and 115kg of water, and add them to the mixer, and stir evenly at high speed to obtain admixture;

[0044] Among them, the composite aggregate is composed of ordinary aggregate and waste rubber aggregate, and the ordinary aggregate and waste rubber aggregate are mixed at a volume ratio of 7:3 to form a composite aggregate. Ordinary aggregate is a single-grained aggregate with a particle size of 5mm-10mm processed from dense and hard rock; rubber aggregate is a waste tire rubber particle with a particle size of 3-5mm. Ordinary aggregates are aggregates in a saturated surface-dry state, and waste tire rubber aggregates are ...

Embodiment 2

[0051] The embodiment of the present invention provides a kind of preparation method of novel pavement permeable concrete product, and preparation method comprises the following steps:

[0052] 1) Weigh 600kg of ordinary aggregate, 400kg of waste rubber aggregate, 300kg of Portland cement, 60kg of fly ash, 60kg of mineral powder, 11.5kg of composite admixture, and 120kg of water, and add them to the mixer, and stir evenly at high speed. get the mixture;

[0053] Among them, the composite aggregate is composed of ordinary aggregate and waste rubber aggregate, and the ordinary aggregate and waste rubber aggregate are mixed at a volume ratio of 6:4 to form a composite aggregate. Ordinary aggregate is a single-grained aggregate with a particle size of 5mm-10mm processed from dense and hard rock; rubber aggregate is a waste tire rubber particle with a particle size of 3-5mm. Ordinary aggregates are aggregates in a saturated surface-dry state, and waste tire rubber aggregates are p...

Embodiment 3

[0060] The embodiment of the present invention provides a kind of preparation method of novel pavement permeable concrete product, and preparation method comprises the following steps:

[0061] 1) Weigh 500kg of ordinary aggregate, 500kg of waste rubber aggregate, 300kg of Portland cement, 45kg of fly ash, 75kg of mineral powder, 8.5kg of composite admixture, and 130kg of water, and add them to the mixer, and stir at a high speed evenly. get the mixture;

[0062] Among them, the composite aggregate is composed of ordinary aggregate and waste rubber aggregate, and the ordinary aggregate and waste rubber aggregate are mixed at a volume ratio of 5:5 to form a composite aggregate. Ordinary aggregate is a single-grained aggregate with a particle size of 5mm-10mm processed from dense and hard rock; rubber aggregate is a waste tire rubber particle with a particle size of 3-5mm. Ordinary aggregates are aggregates in a saturated surface-dry state, and waste tire rubber aggregates are ...

Abstract

The invention provides a novel road surface permeable concrete product and a preparation method of the novel road surface permeable concrete product. The permeable concrete product is prepared from the following raw materials including composite aggregate, a gel material, a composite additive and water at the weight ratio of (2.0 to 3.0) to 1 to (0.003 to 0.03) to (0.25 to 0.35); the composite aggregate is prepared from regenerated aggregate and common aggregate. The permeable concrete product prepared by the invention has water permeability with different gradients and diversified permeable rates; the 28d compressive strength of the prepared permeable concrete product is 5MPa to 15MPa and the permeable rate of the prepared permeable concrete product is 0.5mm / s to 10mm / s. According to the novel road surface permeable concrete product provided by the invention, a construction process can be simplified, and engineering construction can be finished at a single time according to actual engineering requirements; the technical effect which is the same as that of a plurality of times of construction in the prior art can be obtained; when the permeable concrete product is used for paving a side pavement on a road surface, people walking on the road surface can feel comfortable and elastic.

Description

technical field [0001] The invention relates to the technical field of concrete, in particular to a novel pavement permeable concrete product and a preparation method thereof. Background technique [0002] With the development of concrete technology, maintaining ecological balance and realizing sustainable development are also the pursuit goals in the field of building materials. Permeable concrete products are also called porous concrete, or drainage concrete. As an environmentally friendly and ecological road material, it has water permeability, can quickly eliminate water accumulation in roads and squares, and reduce the burden of urban drainage; it can quickly infiltrate rainwater into the ground, replenish groundwater, maintain soil moisture, and maintain the ecology of groundwater and soil Balanced; in terms of heat absorption and heat storage functions, it is close to the ground covered by natural vegetation, adjusts the temperature and humidity of urban space, and a...
