Embodiment Construction

[0052] See the accompanying drawings for the embodiment: This high-strength permeable concrete pavement brick is composed of a base layer 2 and a surface layer 1. The base layer 2 includes small crushed stones 3 and large crushed stones 4, and the cement slurry is wrapped on the aggregate surface composed of large and small crushed stones. , The pores 5 between the aggregates form water-permeable channels. The weight ratio of the base layer is as follows:

[0053] Examples of cement selection: 18%, 19%, 20%, 21%.

[0054] Among them, not more than 30% of cement can be replaced by slag or fly ash.

[0055] Examples of the selection of 3-5mm small gravel: 50%, 51%, 52%, 53%, 54%, 55%;

[0056] Examples of the selection of 7-10mm large gravel: 18%, 19%, 20%, 21%.

[0057] The weight ratio of the above-mentioned 7-10mm large crushed stones to 3-5mm small crushed stones is 1:2, 1:3, 1:4, 1:5, 1:6, 1:7, 1:8, 1:9, 1:10. The size ratio of large particles and small particles can b...

Abstract

The production process of permeable high-strength concrete paver includes the steps of: the first making base layer via mixing cement 18-21 wt%, small rubble of 3-5 mm size 50-55 wt%, large rubble of 7-10 mm size 18-21 wt%, admixture 0.1-6 wt% and water in 0.2-0.23 weight of cement, molding and vibrating to form; and the subsequent making facing layer via mixing cement 15-22 wt%, quartzite 76-85 wt%, admixture 0.1-6 wt%, dispersible latex powder 0.2-0.6 wt% and water in 0.24-0.26 weight of cement, pouring the mixture onto freshly formed base layer, and vibrating to form; demolding; and curing to obtain the finished product. The permeable high-strength concrete paver has high strength, high water permeability and no need of baking, and may be used widely.

Description

(1) Technical field [0001] The invention relates to a floor paving building material, in particular to a floor tile and a production method thereof. (2) Background technology [0002] Floor tiles are subject to greater pressure and therefore require higher strength. The existing floor tiles have high density, such as concrete floor tiles, concrete, polymer synthetic floor tiles, ceramic floor tiles, etc. These floor tiles are all formed from the same material at one time, and the internal material has fewer pores, and the pores are not connected. , impermeable, cut off the communication between the subgrade and the outside world, and destroyed the natural ecological environment. Existing water-permeable floor tiles are made of sintered ceramic materials. Although they have a certain water-permeable function and meet ecological needs, they consume a lot of energy and consume a lot of energy and precious clay resources during firing. If the porosity of the existing concrete ...
