modulus-weight ratio 中文意思是什麼
modulus-weight ratio
解釋
模量重量比-
Gfrp bar is a new antisepsis material and it have many availabilities, such as the resistance to corrosion, high strength - to - weight ratio, low electromagnetic properties and so on. however, to fully replace steel by gfrp bar, some aspects of their behaviour have to be determined, include smooth surface, low bond strength, low modulus of elasticity
玻璃鋼（ gfrp ）筋作為一種新型的防腐筋材，具有許多普通鋼筋所不能比擬的優點，如防腐性能好、抗拉強度高、絕電磁性、易於成型等，但也存在表面光滑、不易與混凝土的粘結、彈性模量較低等缺陷，因此解決玻璃鋼筋與混凝土的粘結強度問題是其技術關鍵。 -
The unconfined compressive strength, shearing strength and permeabi lity of stabilized soils were tested in laboratory, the strength of contaminated composite soils sampled with different ph and soaped in corresponding ph were compared. the results from experiments indicate that there exists a certain relationship between the soft soil properties and the unconfined compressive of grouted soil. with the increase of water content, porosity ratio, degree of porosity, plasticity limit, liquid limit and liquid index, the compressive strength of cement - sodium silicate - stabilized soil decreases, while increases as the bulk weight and compressibility modulus
通過對水泥?水玻璃加固土的無側限抗壓強度試驗，以及用不同酸堿性水製成與養護的固結土所進行強度對比試驗，得出軟土的物理力學性質指標與加固土的抗壓強度之間存在一定的相關關系，即隨著含水量、孔隙比、孔隙度、液塑限及液性指數的增加，水泥?水玻璃加固土的抗壓強度相應地降低；而隨著原狀土的容重、壓縮模量的增加，水泥土的抗壓強度也隨之增加。 -
The test result shows that the water binder ratio is the chief factor in damaging point. the saturation of concrete and the higher degree of saturation in the surface layer of specimens can be used to explain the damage form of specimens in the freezing - thawing, which include change of relative dynamic modulus of elasticity and weight
通過測定飽水受凍6次后混凝土試件的相對動彈性模量，可以計算出混凝土破壞時（ e6 / e0 = 60 % ）相對應的水飽和系數，即極限水飽和系數，試驗結果表明對試件極限水飽和系數而言，水膠比影響顯著。
