expanded aggregate concrete 中文意思是什麼
expanded aggregate concrete
解釋
膨脹骨科混凝土-
It is made of sand, cement and lightweight aggregate, etc. some of the lightweight aggregates include pumice, stuff, expanded clays ( haydite ), etc. lightweight aggregate concrete can provide the same strength as the normal concrete with less weight
輕骨料混凝土是一種用量較大的新型混凝土，其密度在850kg m ~ 3至1950kg m ~ 3之間，由粘土陶粒，粉煤灰陶粒等粗骨料以及常用的砂，水泥，水等材料製作而成。 -
Eight concrete samples of different compound ratio of artificial lightweight aggregate ( coarse aggregate of expanded shale ) and ordinary aggregate, water - reducing admixture, expanding admixture, etc, are compounded firstly, based on the research of main properties such as agitating property, strength, dry surface density and deformation, an optimum compound ratio of the concrete with high strength ( cl40 ), light density ( 1800 ) and slight expand is achieved
首先，採用人造輕骨料（頁巖陶粒）及普通骨料，加入減水劑、膨脹劑等，配製出了八種不同配合比的輕骨料砼與普通砼，並對其和易性、強度、干表觀密度、變形等主要性能進行了試驗研究，得到了強度等級cl40 ，密度等級1800的輕骨料中高強度微膨脹砼最佳配合比。 -
The author of this article used orthogonal test design, arranged the test scheme scientifically, selected material carefully, at last yielded an high strength lightweight aggregate concrete material ( hslacm ), whose compressive strength exceeded 50 mpa and quality under 1950kg / m3, mainly by using 42. 5 ordinary portland cement, expanded fly ash aggregate, silica fume, superplasticizers and so on
本文是在廣泛閱讀國內外有關資料的基礎上，採用正交設計，科學地安排試驗，精心選材，用42 . 5普通硅酸鹽水泥、粉煤灰陶粒、硅灰、高效減水劑等材料，採用一般工藝配製出了一種抗壓強度超過50mpa 、質量低於1950kg m ~ 3的高強輕骨料混凝土材料。 -
Because the experimental bridge is an arcade bridge which is comprised of three four - arched bridges, micro - expansive lightweight concrete, micro - expansive ordinary concrete and ordinary concrete are used in each four - arched bridge respectively in order to comprehend the performance of light expanded lightweight aggregate concrete profoundly and contrast effects of different materials
為了更好地掌握輕質微膨脹砼的加固性能以及對比不同加固材料的加固效果，針對實橋為4孔1聯，共計3聯的特點，各聯的加固分別採用了輕質微膨脹砼、普通微膨脹砼和普通砼三種不同材料。
