Embodiment 1
[0024] 1. Determine raw material quality benchmarks and control indicators:
[0025] (1) Shell aggregate: the shell aggregate of the present invention is a mixed aggregate, which is obtained by stirring and drying the following components in mass fraction: square ring rib snail shell (commonly known as snail) 40% ± 5 %, Bobu Dongfeng snail shell (commonly known as yellow snail) 20% ± 2%, warty lychee snail shell (commonly known as spicy snail, bitter snail) 20% ± 2%, single-toothed snail shell (commonly known as sesame snail) 20% ± 2% .
[0026] In the shell concrete brick body, the strength of the concrete brick body will be reduced when the shell particles with a larger particle size are used. The test shows that the maximum particle size of the shell should be limited to less than 25 mm. Considering the engineering design strength level and the characteristics of various shell mixed aggregates, it is most appropriate to choose the mixed shell aggregate with a maximum parti...
Embodiment 2
[0049] Concrete scheme is with embodiment 1, difference is:
[0050] A concrete brick body with shellfish shells as coarse aggregate, which is prepared by mixing the following proportions: shell aggregate 32 kg, fishing net 20 kg, sand 412 kg, fly ash 128 kg, portland cement 375 kg, water 151 kg. The composition of the shell aggregates: 45% of square ring snail shells, 18% of wavebe Dongfeng snail shells, 18% of verrucous lychee snail shells, and 19% of single tooth snail shells.
[0051] Take the shell aggregate, fishing net, Portland cement and fly ash according to the ratio and mix for 20 minutes at a stirring speed of 80r / min, then add sand and mix for 10 minutes at a stirring speed of 80r / min, and finally add an appropriate amount of water Mix at a stirring speed of 160 r / min for 30 minutes to obtain a slurry.
Embodiment 3
[0053] Concrete scheme is with embodiment 1, difference is:
[0054] A concrete brick body with shellfish shells as coarse aggregate, which is prepared by mixing the following proportions: shell aggregate 30 kg, fishing net 25 kg, sand 410 kg, fly ash 120 kg, silicate 370 kg of cement and 146 kg of water. The composition of shell aggregates: 35% of square ring snail shells, 18% of wavebe Dongfeng snail shells, 18% of verrucous lychee snail shells, and 19% of single tooth snail shells.
[0055] Take the shell aggregate, fishing net, Portland cement and fly ash according to the ratio and mix for 20 minutes at a stirring speed of 65r / min, then add sand and mix for 10 minutes at a stirring speed of 80r / min, and finally add an appropriate amount of water Mix at a stirring speed of 150 r / min for 30 minutes to obtain a slurry.
[0056] The shell aggregate concrete brick body product that above-mentioned embodiment makes has the following advantages after testing:
[0057] (1) The ...
