| Abstract: | The normal temperature strength and collapsibility of sodium silicate sand are always two contradictory property indices in this kind of mounding sand. Some properties of sodium silicate sand hardened by ester were analyzed,and the improvements of the normal temperature strength and collapsibility of sodium silicate sand were investigated. The results show that,the main factors of affecting the normal temperature strength and collapsibility include the sodium silicate binder quality and its quantity added,the raw sand quality, and temperature and humidity in work surrounding. |
