Embodiment 1
[0067] Put the cement, sand, shale ceramsite or granite gravel in the parts by mass shown in Table 1 into the mixer and mix evenly, then add the water in the parts by mass in Table 1 for stirring to obtain shale ceramsite concrete or granite gravel concrete. Among them, the shale ceramsite of concrete 1 to concrete 3 is 5-10mm lightweight aggregate, the strength grades of concrete 1 to concrete 3 are C30, C40 and C50 respectively, and the particle size of granite gravel in concrete 4 is 5-15mm. 4 has a strength class of C60. The mechanical properties of concrete 1 to concrete 4 measured at the age of 28 days are shown in Table 2.
[0068]Compared with concrete 4 of granite crushed stone concrete, the mechanical properties of concrete 1 to concrete 3 are significantly smaller than granite crushed stone concrete, and their density is 21.4%-23.7% lower than that of granite crushed stone concrete, indicating that shale ceramsite is used instead of granite As the coarse aggregate ...
Embodiment 2
[0074] Put the cement, sand, shale ceramsite or granite gravel according to the mass parts shown in Table 3 into the mixer and mix evenly, then add the water in the mass part of Table 3 and stir to obtain shale ceramsite concrete or granite gravel concrete. Among them, the shale ceramsite of Concrete 5 to Concrete 7 is 5-20mm lightweight aggregate, the strength grades of Concrete 5 to Concrete 7 are C30, C40 and C50 respectively, and the particle size of granite gravel in Concrete 8 is 5-15mm. The strength class of 8 is C60. The mechanical properties of concrete 5 to concrete 8 measured at the age of 28 days are shown in Table 4.
[0075] Compared with concrete 8 of granite crushed stone concrete, the mechanical properties of concrete 5 to concrete 7 are significantly smaller than granite crushed stone concrete in terms of elastic modulus and density, and its density is 22.3% to 25.1% lower than that of granite crushed stone concrete. The strength is significantly greater tha...
