water cycle test
解釋
水循環試驗-
Under the different freezing - thawing cycle circumstance, three factors of water binder ratio, air content and mineral admixture are analyzed by using the method of orthogonal table. the test results show that the chief influencing factor is the water binder ratio in water freezing - thawing cycle circumstance, and in salt freezing - thawing cycle circumstance is the air content. this could illustrate that entraining air into concrete can improve the frost resistance of concrete effectively in salt freezing - thawing cycle
分析了在純水和3 . 5 % nacl溶液中受凍后，水膠比、含氣量和摻合料對混凝土飽和系數及變化速率的影響規律，試驗結果表明水膠比對混凝土水凍時的飽和系數及變化速率影響顯著，而鹽凍情況下含氣量則是主要影響因素，說明引氣能顯著提高混凝土的抗鹽凍性能。 -
Considering the similitude law for shaking table test, we study the test results and obtain some conclusions which are a ) generally, the silty soil in test box liquefies and the liquefied time has relation with the amplitude of acceleration, b ) when the intensity is on and above eight degree, the silty soil deposit will be liquefied dramatically, c ) the relationship of the pore water pressure is relevant to the cycle loading which represents when the cycle loading ranges from little to great, the relationship is represent as a concave curve, or else as a protruding curve and tends to stability. ( 3 ) based on the triaxial compression test and the resonant column test, some studies are made such as a ) the duncan - chang parameters of constitutive model, b ) the dynamic shear modulus ratio and c ) the damping ratio of the site soil deposits. in order to deal with the test data, a computer program is compiled
（ 2 ）利用小型振動臺進行了k _ 0固結狀態下粉土的振動液化模擬研究，通過分析正弦荷載作用下的試驗資料，驗證了粉土的孔隙水壓力增長模式的合理性；從微分方程推導了基於土體振動臺模型試驗的相似律，並從模型實體、孔壓時程曲線和相似律等方面做出了分析，得出了如下結論：在小型振動臺試驗中，模型箱中的粉土都發生了液化，液化的時刻和輸入加速度幅值有關，而對頻率的變化不太敏感；粉土在相當於8 9度地震烈度的加速度幅值作用下可能產生嚴重的液化；孔壓的增長曲線形狀與施加的荷載有關：當施加荷載為由小到大的形式時，曲線形狀為上凹的曲線；當施加荷載為等幅的正弦荷載或荷載幅值由大到小時，曲線形狀為上凸的曲線，且逐漸趨于穩定。 -

水冷二沖程汽油機油互溶性測定法 -
Test results show chloride ions critical content in immersion conditions is always larger than that in cycle of dry and wet for the same concrete, that is, test conditions affects chloride ions critical content value. in the same conditions, water / binder ratio obviously affects chloride ions critical content, but the influence of fly ash or slag on chloride ions critical content is not obvious. it is obtained the equation that chloride ions critical content change with water / binder ratio through linear fitting experiment data
結果表明，同技術條件的混凝土試件，在全浸泡條件下的氯離子臨界濃度均要大於干濕循環條件下的，即臨界濃度大小受到試驗條件的影響；相同的試驗條件下，水膠比對氯離子臨界濃度大小有顯著地影響，而摻入適量的粉煤灰或礦渣粉對氯離子臨界濃度無明顯地影響。
