摘 要:研究了玄武岩纤维(BF)、可再分散乳胶粉、羟乙基甲基纤维素醚(HEMC)、UEA膨胀剂和十二烷基硫酸钠(K12)对混凝土力学性能和抗裂性能的影响。结果表明:随着可再分散乳胶粉掺量的增加,混凝土的抗压强度和劈裂抗拉强度基本呈降低趋势,拉压比先减小后增大;随着BF掺量的增加,混凝土的抗压强度和劈裂抗拉强度先增大后减小,拉压比基本呈增大趋势,抗裂性能提升;复掺BF、可再分散乳胶粉、HEMC、UEA膨胀剂和K12 时,混凝土的抗压强度和劈裂抗拉强度较复掺BF、可再分散乳胶粉、HEMC和UEA膨胀剂时有所降低,但拉压比增大,抗裂性能显著提升。
Abstract: The effects of basalt fiber(BF), redispersible latex powder, hydroxyethyl methyl cellulose ether (HEMC), UEA expansion agent and sodium dodecyl sulfate (K12) on the mechanical properties and crack resistance of concrete were studied. The results show that the compressive strength and splitting tensile strength of concrete basically decrease with the increase of redispersible latex powder content, and the tensile compression ratio decreases first and then increases. With the increase of BF content, the compressive strength and splitting tensile strength of concrete first increase and then decrease, the tension compression ratio basically increases, and the crack resistance is improved. When mixed with BF, redispersible latex powder, HEMC, UEA expansion agent and K12, the compressive strength and splitting tensile strength of concrete are lower than those of mixed with BF, redispersible latex powder, HEMC and UEA expansion agent, but the tensile compression ratio is increased, and the crack resistance is significantly improved.
