Embodiment 1

[0033] High-strength fiber permeable concrete raw materials (parts by weight): 100 parts of PO 42.5R cement, 500 parts of granite crushed stone, 8 parts of fly ash, 3 parts of polypropylene fiber, 5.4 parts of water reducing agent, 18 parts of nano composite filler, 33 parts of water .

[0034] The water reducing agent consists of sodium tris(1-methylethyl)naphthalene sulfonate, sodium 6-hydroxy-2-naphthalene sulfonate, and sodium 2,6-di-tert-butyl naphthalene sulfonate in a mass ratio of 1: 1:1 stir and mix evenly to obtain.

[0035] The nano composite filler is obtained by mixing and uniformly mixing titanium phosphate, copper tungstate and copper oxalate in a mass ratio of 1:1:1.

[0036] Preparation of high-strength fiber permeable concrete: add water reducing agent into water and mix evenly to obtain a mixed liquid; add PO 42.5R cement, granite crushed stone, polypropylene fiber, fly ash, and nano composite filler into a concrete mixer and mix evenly. Then add the mixed soluti...

Embodiment 2

[0038] It is basically the same as Example 1, except that the water reducing agent is mixed with sodium 6-hydroxy-2-naphthalene sulfonate and sodium 2,6-di-tert-butyl naphthalene sulfonate at a mass ratio of 1:1. Get it evenly. The high-strength fiber permeable concrete of Example 2 was obtained.

Embodiment 3

[0040] It is basically the same as Example 1, except that the water reducing agent is composed of sodium tris(1-methylethyl)naphthalene sulfonate and sodium 2,6-di-tert-butyl naphthalene sulfonate in a mass ratio of 1: 1 Stir and mix evenly to obtain. The high-strength fiber permeable concrete of Example 3 was obtained.

Abstract

The invention discloses high-strength fiber permeable concrete. The high-strength fiber permeable concrete comprises, by weight, 95-105 parts of cement, 440-540 parts of granite broken stone, 1-10 parts of coal ash, 1-5 parts of polypropylene fibers, 1-10 parts of water reducing agents, 10-30 parts of nanometer composite fillers and 28-38 parts of water. The high-strength fiber permeable concrete has the advantages that the types and the usage of the water reducing agents and the nanometer composite fillers which are suitable for the high-strength fiber permeable concrete are optimally selected by means of reasonable matching, accordingly, the high-strength fiber permeable concrete is excellent in compressive strength and has an excellent permeability coefficient, diversified engineering demands with requirements on the permeability of concrete can be met, and the high-strength fiber permeable concrete is favorable for maintaining ecological balance and implementing sustainable development.

Description

Technical field [0001] The invention relates to the technical field of concrete, in particular to a high-strength fiber permeable concrete. Background technique [0002] In the process of urbanization, the surface of modern cities is gradually hardened and covered by water-blocking materials such as buildings and concrete, forming an ecological "man-made desert". Convenient transportation facilities and smooth roads are bringing people to travel. At the same time of great convenience, these impervious roads also have a great negative impact on the urban ecological environment. First of all, traditional ground paving emphasizes the durability and usability of the ground, but the impermeability of this pavement completely blocks the precious natural precipitation from the underlying soil and groundwater, and most of the precipitation passes through the urban drainage system. The drainage of pipe networks into rivers, lakes and seas and other surface water sources, combined with th...
