［摘要］為了完善實(shí)際工程中對(duì)裝配式建筑套筒灌漿料強(qiáng)度的檢驗(yàn)，選用了國(guó)內(nèi)五種不同型號(hào)的套筒灌漿料，在不同水料比下分別設(shè)計(jì)制作了實(shí)際工況下養(yǎng)護(hù)的35個(gè)高徑比1∶1的圓柱體小芯樣和9個(gè)標(biāo)準(zhǔn)試件進(jìn)行抗壓強(qiáng)度試驗(yàn)。經(jīng)統(tǒng)計(jì)分析，小芯樣試件抗壓強(qiáng)度值均基本服從正態(tài)分布。根據(jù)水料比的變化，線性擬合出兩種試件抗壓強(qiáng)度關(guān)系曲線，并建立了實(shí)際工況下小芯樣試件和標(biāo)準(zhǔn)試件抗壓強(qiáng)度換算公式。為驗(yàn)證公式可靠性，另取三家灌漿料數(shù)據(jù)對(duì)其檢驗(yàn)，結(jié)果表明灌漿料抗壓強(qiáng)度公式計(jì)算值與試驗(yàn)值接近，公式匹配度良好，可為工程中檢測(cè)裝配式建筑套筒灌漿料實(shí)體強(qiáng)度提供參考。

Abstract:In order to improve the inspection of the strength of the prefabricated building sleeve grout in the actual project, five different types of sleeve grouting materials were selected in China, and 35 cylinder core samples with a height-to-diameter ratio of 1∶1 and nine standard specimens were designed and manufactured in actual working conditions under different water-to-material ratios for compressive strength tests. According to statistical analysis, the compressive strength values of core specimens are basically obeyed by normal distribution. According to the change of water-to-material ratio, the relationship between the compressive strength of the two specimens was linearly fitted, and the fitting formula of the compressive strength of the small core specimen and the standard specimen under actual working conditions was obtained. In order to explain the reliability of the formula, the other three grouting data were used to test. The results show that the calculated value of the grouting compressive strength formula is close to the experimental value. The formula matching degree is good. It can provide a reference for testing the solid strength of prefabricated construction sleeve grouting in engineering.

Keywords:sleeve grouting materials; fitting formula; compressive strength test; prefabricated building
