expanding agent meaning in English
发泡剂
膨胀剂
Examples
- The pore of schsc is smaller and more homogeneous than that of nhsc . fourth , the contribution to concrete microstructure of the expanding agent is very little at early ages ; however it is obvious at late ages to a certain extent . fifth , for the contribution of the mixing content of fly ash is that the contribution to the degree of early age concrete hydration is obvious to some extent , and that the contribution to the shape of hydrate of concrete is obvious
实验研究表明:自密实混凝土由于粉煤灰的掺量较高，其早期的水化程度较低，但后期其细观结构较普通混凝土好；自密实混凝土的骨料界面过渡区与水泥石的差别始终较普通混凝土小，其孔隙较普通混凝土小而均匀；膨胀剂对自密实混凝土早期的细观结构影响不大，但对后期的细观结构有一定影响；粉煤灰掺量对自密实混凝土的早期水化程度有一定影响，且其对自密实混凝土水化物的形态影响较大。 - The main content is : splitting tensile experiments were carried out about the standardized cube bonding specimens ( 150x 150x 150mm3 ) of the new - old concrete after high temperature . the temperature is divided into 9 groups from normal atmospheric temperature to 900 , the cooling styles are natural cooling and spraying water cooling ; different interfacial treating methods : brushed with steel - wire brush , man - made chiseling ( not evenly ) , man - made chiseling ( quite evenly ) ; different interfacial agents : no interfacial agent , neat cement paste , cement paste mixed with 10 % expanding agent
主要内容有：本文对75个高温作用后的标准立方体新老混凝土粘结试件进行了劈拉试验，温度从常温到900c分9个温度段，降温方式分自然冷却和喷水冷却两种。着重考察了温度、降温方式、界面粗糙度及界面剂对新老混凝土粘结劈拉强度的影响规律，阐述了高温后粘结强度下降的机理。 - ( 2 ) interfacial agents this experiment adopts three types of interfacial agents : no interfacial agent , neat cement paste which has the same water - cement ratio with the new concrete , cement paste mixed with 10 % expanding agent which has the same ratio with the new concrete ( which is called cement paste mixed with expanding agent for short ) . the thickness of the interfacial agent is 2 ~ 3mm
（ 2 ）粘结剂本试验采用三种粘结剂：无粘结剂、同新混凝土相同水灰比的水泥净浆、掺10 u型膨胀剂的同新混凝土相同水灰比的水泥净浆（以下简称水泥膨浆） 。界面剂的厚度一般为2 3mm 。 - The main work done in this paper is as follows : ( 1 ) simulate the temperature field of basement wall by ansys software , sum up the characteristics of the temperature field of basement wall , and analyze the influence of the types of the molding board , environmental change and cement content ; ( 2 ) the whole simulation analysis process of early - age concrete stress field is realized by sub - development of ansys , and cts - ansys software is developed with fortran ; ( 3 ) based on the cause of cracking , the influence of the thickness of the wall , length , bar arrangement , mix proportion , expanding agent , etc , on the wall stress due to concrete creep and temperature change is analyzed
