Problems solved by technology

However, the biggest disadvantage of ordinary cement concrete is that the appearance color is monotonous, dark and dull, which gives people a sense of depression.
[0003] After retrieval, the Chinese patent application number is CN201910523743.X, which discloses a preparation method of colored concrete, comprising the following steps: 200-250 parts by weight of white Portland cement raw material, 10-15 parts by weight of pigment, and calcined into colored Portland cement clinker; add 20-25 parts by weight of gypsum to the fired colored Portland cement clinker, and grind to form colored Portland cement. Substances that improve the compressive and cracking resistance of concrete, so there are still problems of low compressive and cracking resistance and corrosion resistance of concrete

Embodiment 1

[0031] A preparation method of anti-compression and anti-crack colored luminous concrete, such as figure 1 shown, including the following steps:

[0032] S1: Pour Portland cement, pigment, coarse aggregate, fine aggregate and metal fiber into a mixer for stirring and mixing to obtain a cement mixture;

[0033] S2: Pour water reducing agent and water into the cement mixture, and continue stirring. The mass ratio of water reducing agent to cement mixture is 2-3%, and the mass ratio of water to cement mixture is 35-45% %;

[0034] S3: pre-stirring the binder, fluorite and glass fiber, the mass ratio of the binder, fluorite and glass fiber is 1:2-3:5-6;

[0035] S4: Pour the stirred and mixed binder, fluorite and glass fiber into the cement mixture, and at the same time add water for the second time and then stir and mix;

[0036] S5: After stirring and mixing, let stand to settle and exhaust, then continue to stir for 15-20 minutes to prepare colored concrete;

[0037] S6: Pl...

Embodiment 2

[0054] Portland cement 100-120 parts, pigment 20-40 parts, coarse aggregate 100-120 parts, fine aggregate 150-160 parts, binder 10-15 parts, fluorite 10-15 parts and water 100- 150 parts were poured into a mixer for mixing and then poured into a mold for 28 days to make a colored concrete slab, and then the colored concrete slab was tested for compressive and flexural strength, and the data for compressive and flexural strength were: Compressive strength - 33.5MPa. Bending strength - 5.0MPa.

Embodiment 3

[0056] Portland cement 100-120 parts, pigment 20-40 parts, coarse aggregate 100-120 parts, fine aggregate 150-160 parts, binder 10-15 parts, fluorite 10-15 parts, glass fiber 20 parts -25 parts of straight steel fibers with a dosage of 20-30kg / m3 concrete and 100-150 parts of water are poured into a mixer for mixing, and then poured into a mold for 28 days to make a colored concrete slab, and then the colored concrete slab The compressive and flexural strength tests were carried out, and the data obtained for the compressive and flexural strength were: compressive strength--55.5MPa. Bending strength - 6.3MPa.

[0057] Then according to embodiment 1, colored concrete was made, poured into the mold and made colored concrete slab after 28 days, then the colored concrete slab was tested for compressive and flexural strength, and the data obtained for compressive and flexural strength were: compressive strength Strength - 65.6MPa. Bending strength--7.5MPa, the compressive and ben...

Abstract

The invention discloses a preparation method of compression-resistant and crack-resistant colored luminous concrete, and relates to the technical field of concrete. The invention aims to solve the problems of low compression resistance, crack resistance and corrosion resistance of luminous concrete. The method specifically comprises the following steps that Portland cement, pigment, coarse aggregate, fine aggregate and metal fibers are poured into a stirrer together to be stirred and mixed, a cement mixture is obtained, a water reducing agent and water are poured into the cement mixture, stirring continues to be conducted, the mass ratio of the water reducing agent to the cement mixture is 2%-3%, and the mass ratio of the water to the cement mixture is 35%-45%; the binder, the fluorite and the glass fiber are pre-stirred; according to the invention, the binder prepared from alumina powder, montmorillonite and epoxy resin is added into the concrete, so that the overall corrosion resistance and aging resistance of the concrete are effectively improved, and meanwhile, the added alumina powder can effectively improve the hardness of the epoxy resin, so that the overall strength of the concrete is further improved.

Description

technical field [0001] The invention relates to the technical field of concrete, in particular to a preparation method of compression-resistant and crack-resistant colored luminous concrete. Background technique [0002] Ordinary cement concrete is the most important building material in the world today. It can not only be used as a building material, but also has a certain decorative effect. Due to the good plasticity of concrete, it can be poured into various complex shapes, mainly used for pouring of road pavement, bridges, docks, etc.; in urban road engineering, mainly used for urban roads, sculptures and other artistic creations. However, the biggest disadvantage of ordinary cement concrete is that the appearance is monotonous, dark and dull, giving people a sense of depression. Therefore, the application of colored concrete has received widespread attention. [0003] After retrieval, the Chinese patent application number is CN201910523743.X, which discloses a prepara...
