研究了聚乙烯醇（PVA）纖維的長度（3 mm、6 mm、12 mm）和體積摻量（0、0.1%、0.3%、0.5%、1.0%、1.5%、2.0%）對輕骨料混凝土抗壓和劈裂抗拉性能的影響，并對PVA纖維輕骨料混凝土的抗壓強度尺寸效應進行了研究。結果表明：隨著PVA纖維長度和體積摻量的增加，輕骨料混凝土的抗壓強度和劈裂抗拉強度基本均呈降低趨勢，當PVA纖維長度為3 mm、體積摻量為0.1%時，輕骨料混凝土的抗壓強度和劈裂抗拉強度達到最大；PVA纖維輕骨料混凝土的抗壓強度尺寸效應較為顯著，建立的PVA纖維輕骨料混凝土抗壓強度尺寸效應公式與試驗結果吻合良好。
The effects of length(3 mm, 6 mm, 12 mm) and volume content(0, 0.1%, 0.3%, 0.5%, 1.0%, 1.5%, 2.0%) of polyvinyl alcohol(PVA) fibers on the compressive and splitting tensile properties of lightweight aggregate concrete were studied, and the size effect of compressive strength of PVA fiber lightweight aggregate concrete was studied. The results show that with the increase of PVA fiber length and volume content, the compressive strength and splitting tensile strength of lightweight aggregate concrete basically show a decreasing trend. When the PVA fiber length is 3 mm and the volume content is 0.1%, the compressive strength and splitting tensile strength of lightweight aggregate concrete reach the maximum. The size effect of compressive strength of PVA fiber lightweight aggregate concrete is significant. The established formula of size effect of compressive strength of PVA fiber lightweight aggregate concrete is in good agreement with the experimental results.
