Factors which can accelerate the early hydration of cement, the setting in particular, such as excessively high c3a content, too low so3 content, high alkali content and the blending of pozzolana with large inner specific surface area, etc., will result in poor compatibility of the superplasticizer with cement
凡是加速水泥初期水化的因素，特別是使水泥凝結加速的因素如c3a含量過高、 so3摻量過少、堿含量高以及摻入內比表面積大的火山灰質混合材等均使水泥與超塑化劑的相適應性變差。 -
The study reveals that the infected soil is of high ph value and low effective iron content and the afore - said infected trees and plants suffer from a deficiency of iron for their normal growth, as the alkali soil is lack of effective iron, and the insufficiency in turn weakens the rhizome of the trees to absorb iron effectively and impedes the movement of iron along the trunk and branches
結果表明：舟山市朱家尖苗木基地紅楠黃化是由於基地土壤呈堿性，致使土壤中缺少有效態鐵，影響了根系對鐵的吸收和鐵在樹體內的移動及有效性，不能滿足紅楠正常生長對鐵的需要而引起的缺綠黃化癥。 -
Comparing with the granitoid from jiaodong guojialing in mineralogy, the minerals in the granitoid in nimu - qushui granitoid crystallized in the environment of oxidization, the granitoid has a characteristic of rich volatile components and a high content of alkali, the rock - forming minerals and accessory minerals have a characteristic of i - type granite, and the granite shows a characteristic in favor of an and cu ore formation
通過與膠東郭家嶺地區的花崗巖類的礦物學進行對比，可知本區花崗巖類礦物結晶時處于氧化狀態，具有富含揮發分的特徵，堿質含量高，造巖礦物及副礦物表現出型花崗巖特徵，具有殼幔混源物質，表現出有利於金、銅礦形成的花崗巖類的礦物特徵。 -
Abstract : controlling aar with high quality i grade fly ash has been researched. the result shows that the content is more important than the quality for the effect on controlling aar. the solubility of the fly ash contained alkali is inquired in differ alkali concentration solution. the mechanism of low content accelerating swell and yet high content controlling swell is discussed when controlling aar with the fly ash contained high alkali content
文摘:研究優質級粉煤灰對堿骨料反應的抑制效果，結果表明，用粉煤灰抑制堿骨料反應，其摻量因素的影響大於品質因素的影響；探討了粉煤灰中的堿在不同濃度堿溶液中的溶出情況及用高堿含量粉煤灰抑制堿骨料反應時，低摻量促進膨脹，高摻量抑制膨脹的機理。
