Methods of test for masonry units - determination of water absorption of aggregate concrete, manufactured stone and natural stone masonry units due to capillary action and the initial rate of water absorption of clay masonry units
圬工砌塊的試驗方法.混凝土人造石和天然石圬工砌塊因毛細作用的吸水率及粘土圬工砌塊吸水初速的測定 -
Methods of test for masonry units - part 11 : determination of water absorption of aggregate concrete, manufactured stone and natural stone masonry units due to capillary action and the initial rate of water absorption of clay masonry units
圬工單位的試驗方法.第11部分:集料混凝土人造石和天然石圬工單位因毛細作用的吸水率及粘土圬工單位吸水初速的測定 -
Lightweight aggregate concrete ( lac ) is one of concrete that uses artificial or natural lightweight aggregate instead of normal aggregate
輕骨料混凝土是一種利用人造或者天然輕質骨料替代普通密度骨料的混凝土。 -
Compared with natural aggregate, the accumulation density of recycled aggregate is lower, the water absorption is higher, the surface is rougher and the crush index is greater, the performance of concrete changes evidently
再生骨料與天然骨料相比，堆積密度小、吸水率高、表面粗糙且壓碎指標大，對再生混凝土性能影響明顯。 -
Using the contrast tests of 13 recycled aggregate concrete beams and natural aggregate concrete beams, the effects of replacement ratio of recycled coarse aggregate and shear - span ratio on the characters of shear capacity and deformability of recycled concrete beams are investigated
摘要通過13根再生混凝土梁與普通混凝土梁的對比試驗，對再生粗骨料取代率、剪跨比等因素對再生混凝土梁斜截面受力和變形性能的影響進行探討。 -
The test result shows the deflection and diagonal crack of recycled aggregate concrete beams are bigger than natural aggregate concrete beams, the shear capacity of recycled concrete beams reduces with the increase of recycled coarse aggregate content, the shear capacity reduces with the increase of shear - span ratio
試驗結果表明：再生混凝土梁比普通混凝土梁變形和斜裂縫寬度稍大；隨著再生粗骨料取代率的增加，再生混凝土梁的抗剪承載力略有下降的趨勢；隨著剪跨比的增加，抗剪承載力減小。
