low cement content 中文意思是什麼
low cement content
解釋
低水泥用量-
According to rock and mineral analysis, the formation consists dominantly of detrital feldspathic fine - sandstone with medium and silt sandstone secondly. lithologically, the content quartz is lower than those of feldspar and detritus, and the cement is dominated by clay, which gives the feature of low compositional maturity and low textural maturity
館上段儲層巖性以巖屑質長石細砂巖為主，其次為中細砂巖和粉砂巖，巖石中石英含量低，而長石、巖屑含量高，膠結物以泥質為主，表現出低成分成熟度和低結構成熟度的特點。 -
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。 -
Based on above, the characteristics of hydration hardening process and microstructure of hsc as well as the interfacial layer between cement paste and coarse aggregate are investigated under low water cement ratio, high content superplasticiser and with one kind or more than one kind of mineral materials condition, the reaction mechanisms of different mineral materials are also discussed
研究了不同水膠比、復合緩凝成分高效減水劑及礦物摻合料的摻加方式、摻量對高強混凝土水泥漿體水化放熱過程和水泥漿體的水化熱、水化放熱速率以及最高溫升的影響規律。探明了高強混凝土中水泥漿體的水化硬化過程、礦物摻合料之間的相互作用機理。 -
The good quality 425r silicate cement and 525 silicate cement, which are produced by the use of rotary kiln and up to the national standard gb175 - 92, are particularly suitable for the construction of buildings for civil use, airport, road, port, and dam because of its good early strength, quick condensation, good freeze and abrasive resistance, and low basicity content
我公司出品的425r 525普通硅酸鹽水泥，系採用國濕法旋窯生產工藝，按國家標準gb175 - 92精心組織生產。具有早期強度高凝結硬化快抗凍性好耐磨性好含堿量低等特點，曾獲得福建省優質產品稱號。 -
Namely : ( 1 ) the cf can be dispersed by methyl cellulose and superfine silica fume used together and the electrical resistivity is low. so it provides a good way for cf dispersion ; ( 2 ) the results on cf cement - based fgm include four aspects. firstly, the electrical resistivity is influenced little by cf content increase after the conductive circuit formation
研究結果表明： （ 1 ）採用甲基纖維素和超細硅粉復合摻拌的分散辦法，使纖維充分分散，導電效果比較理想，為纖維分散提供了一條優良的途徑； （ 2 ）碳纖維混凝土中，導電網路形成后，纖維含量繼續增加對電阻率的影響不大。
