Embodiment 1
[0045] A high-strength, high-elastic-modulus high-damping concrete whose proportioning conditions are shown in Table 3, and the specific preparation steps are as follows:
[0046] 1) Weigh each raw material according to the proportion, and before concrete mixing, first wipe the mold clean, remove the sundries in the mold, and apply a layer of release agent in the mold;
[0047] 2) Mix the weighed natural sand, cement, fly ash, mineral powder, silicon powder, graphite, cement-based permeable crystalline waterproof material and stir for 30s with a forced mixer to make the cement and other solid materials uniform in the aggregate For distribution, add water, water reducer, styrene-acrylic emulsion, carboxylated styrene-butadiene latex and stir for 2 minutes, and finally add steel fiber and stir for 30 seconds to obtain a concrete mixture;
[0048] 3) The obtained concrete mixture is divided into two layers, each layer is about 1 / 2, and each layer is inserted and rammed about 2 to...
Embodiment 2
[0052] The preparation method of the high damping concrete described in Example 2 is roughly the same as that of Example 1, except that the formula conditions recorded in Table 2 are used respectively, and the strength grade of the obtained concrete is C40.
Embodiment 3
[0054] The preparation method of the high damping concrete described in Example 3 is roughly the same as that of Example 1, except that the formula conditions recorded in Table 2 are used respectively, and the strength grade of the obtained concrete is C40.
