【摘要】:參照GB/T 2542—2012《砌墻磚試驗方法》,對復摻纖維與水泥、單摻水泥、單摻砂等3種尺寸為240 mm×115 mm×90 mm的30個改性機制生土磚試件進行抗壓強度試驗,從試件的破壞形態(tài)、荷載-位移曲線、極限強度以及數(shù)據(jù)分布情況等方面考察試驗方法的可行性。研究表明:3種試件在該試驗方法下強度值分布合理,受力過程、破壞形態(tài)符合生土塊材軸心受壓規(guī)律,抗壓強度數(shù)據(jù)整體表現(xiàn)穩(wěn)定,表明按GB/T 2542—2012得出的結(jié)果能真實反映機制生土磚的抗壓強度,可作為機制生土磚的抗壓強度標準試驗方法。
[Abstract]:With reference to GB/T 2542-2012, the compressive strength tests of 30 modified raw soil brick specimens with the size of 240mm 脳 115mm 脳 90mm were carried out. The feasibility of the test method was investigated in terms of load-displacement curve, ultimate strength and data distribution. The results show that the strength distribution of the three kinds of specimens is reasonable, the stress process and the failure pattern are in accordance with the axial compression law of raw soil blocks, and the compressive strength data are stable as a whole. It is shown that the results obtained from GB/T 2542-2012 can truly reflect the compressive strength of machine-made soil bricks and can be used as the standard test methods for the compressive strength of machine-made soil bricks.
