Mechanical performance , frost resistance and abrasion resistance of concrete with fly ash , air entraining agent and four kinds of inorganic salts including sodium sulfate , sodium nitrite , calcium nitrite and sodium chloride are mainly studied in this paper 本文研究了在路面水泥混凝土中摻入粉煤灰、引氣劑和四種無機鹽( na2so4 、 nano2 、 ca ( no2 ) 2和nacl )后,混凝土的力學性能、抗鹽凍剝蝕能力和耐磨性等性能的變化規律。

Adding air - entrained agent can enhance the heat preservation performance of pumice concrete and improve its durability . using water - reducing admixture can improve the performance of pumice concrete , but the quantum is bigger than in the ordinary concrete 為獲得良好的物理力學性能并提高混凝土的和易性,摻加減水劑對其性能改進具有明顯的技術經濟效果,其摻量要比普通混凝土稍高。

The problem of the reinforcement corrosion has already drawn the wide attention of the academic circles , and has been conducted the massive research . however the reinforcement corrosion of air - entrained concrete has not been taken into the systematic research 國內外學者對普通鋼筋混凝土進行了大量研究,得出了很多重要的結論,但對引氣混凝土的抗鋼筋銹蝕性能研究則較少。

It has also been alleged that the haarp , or “ high altitude active auroral research project “ , which can use the ionosphere as a giant antenna for broadcasting signals , may be used to entrain various mind / body states in large areas of the planet 也有人指稱haarp ,或“高頻率活躍極光研究計劃“ ,可利用電離層作為一個廣播信號巨型天線,可用于在地球的大范圍誘導大腦/身體狀態。

The application research of water - soluble polymer in concrete admixtures , in which including water - reducer , air - entraining agent , shrinkage - reducing agent , anti - washout admixture and corrosion inhibitors were summarized 摘要綜述了水性高分子材料在混凝土外加劑中的研究及應用情況,其中包括減水劑、引氣劑、減縮劑、水下不分散劑及阻銹劑等。

The influence of inorganic salts on mechanical performance of air entrainment concrete is similar with non - air entraining concrete . all those inorganic salts can improve the frost resistance of concrete except calcium nitrite 抗鹽凍剝蝕能力方面,除摻有ca ( no2 ) 2的混凝土表現了較大的剝落量外,其它的混凝土都有較好的抗鹽凍剝蝕能力。

The application status , research and development of entrain bed coal gasification process were introduced briefly . its superiority and existent problems were analyzed and improvement suggestion was put forward also 摘要簡述了氣流床煤氣化技術的應用狀況和研究進展,分析了干煤粉氣化的技術優勢和存在的問題,并提出一些改進建議。

Sand - entraining could make microbes in maternal fermented grains achieve pit entry fermentation by means of inoculation , which was simple and feasible and had satisfactory effects in the improvement of top - grade product rate 通過夾沙發酵使母糟中的微生物以接種方式入池發酵,達到提高優級品率的目的,既簡單可行,效果又明顯。

On the basis of considering environmental protection , resources comprehensive utilization and industrial policies , the method of using tailing sand to produce air - entraining concrete was put forward 摘要本文在全面考慮環境保護、資源綜合利用和產業政策的基礎上,提出了以尾礦砂為原料生產加氣混凝土的綜合利用方法。

Various sand - entraining fermentation tests suggested that sand - entraining ( 20 % of the amount of quality maternal fermented grains ) could increase top - grade product rate by about 5 % 經過各種夾沙發酵試驗表明,按投糧數20 %的優質母糟夾沙,可以提高優級品率5 %左右。

This is generally accomplished by using water - reducing admixtures . specify air - entrained concrete for outdoor slabs subjected to freezing weather 也可以使用更高坍落度(的混凝土) ,但(制作混凝土的)混合物必須是設計用于制作不過量泌水和/或分離(混凝土)的(混合物)

Emhydr hr oils have excellent oxidation stability and demulsibility , enabling ready separation of entrained water and giving long life without formation of harmful sludge Emhydr hr具有優異的抗氧化與抗乳化性,能輕易祛除水份,經久使用而不會生成油泥。

As alkalies in the coal dust ash dissolve out and carbonates are entrained into the system , serious scaling occurs in the cooling system of the dust collector 摘要由于粉煤灰中堿性物的溶出及碳酸鹽帶入系統,導致除塵冷卻水系統存在嚴重的結垢問題。
