Embodiment 1
[0028] A stone chip concrete mortar, the components of the mortar include water, cement, sand and stone powder, and the stone powder is the powder produced during the crushing process of pebbles;
[0029] In terms of parts by mass, the relationship between the water, cement, sand and stone powder is as follows: 100 parts of the water, 200-300 parts of the cement, 150-230 parts of the sand, and 10-20 parts of the stone powder ;
[0030] The particle size of the stone powder is less than 0.08 mm.
[0031] Specifically, the above stone powder can play the role of admixture in the concrete mortar components, and the stone powder particles can make the stone chip concrete mortar mixture have good cohesion, and can achieve the purpose of improving the overall workability of the mortar;
[0032] At the same time, stone powder particles can fill the pores in the mortar, which can enhance the compactness of cement and aggregate, and can improve the impermeability of concrete; the ston...
Embodiment 2
[0038] This embodiment further optimizes this case on the basis of Example 1: the components of the mortar also include coarse aggregates, the coarse aggregates include stone chips and crushed stones, and in parts by mass, the water, The relationship between stone chips and coarse aggregate is as follows: 100 parts of the water, 60-70 parts of the stone chips, and 600-800 parts of the gravel;
[0039]Both the stone chips and gravel are obtained by crushing pebbles, and the particle size of the stone chips is between 0.5 mm and 5 mm, and the particle size of the gravel is between 5 mm and 31.5 mm. This scheme makes full use of the products obtained from pebble crushing, among which, the pebble crushing products account for more than 70% of the concrete mortar, so that large-diameter pebbles can be well used in engineering construction; at the same time, using the above Component ratio, in the case of cement using conventional portland cement, C25 concrete can be obtained. Ther...
Embodiment 3
[0043] On the basis of Example 1, this embodiment provides a specific implementation method: the stone chip concrete mortar is mixed with the following components: 175kg of water, 461kg of cement, 356kg of sand, 30kg of stone powder, 140kg of stone chips, crushed Stone 1252kg, water reducing agent 4.61kg, air-entraining agent 1.38kg, wherein, the cement is Portland cement, the sand is river sand collected from the river bed, and the stone powder, stone chips and gravel are all made of pebbles It is obtained by crushing, and the particle size of the stone chips is between 0.5 mm and 5 mm, the particle size of the crushed stone is between 5 mm and 31.5 mm, and the pebbles are pebbles collected from the river bed, and the above formula C25 concrete can be obtained with a specific mortar, and the pressure bleeding rate of the obtained concrete is about 3%.
