The effects of different curing systems on the properties of high volume fine mineral powder RPC (reactive powder concrete) and the appearances of hydrates were studied. The experimental results show that dry-heatin...
The hydrating products and microstructure of permeability resisting portland cement have been studied by x-ray diffraction (XRD) and electron microscopy (EM). The hydrates such as calcium silicates hydrate and calcium...
The mechanical properties and durability (mainly frost - resistance and carbonation resistance) of fly ash - CaO - CaSO//4 center dot 2H//2O hardened paste are studied. The relationship among durability of hardened f...
In this paper,the macro properties and hy-dration phases of lime-sand silicate concrete which NaOH of various contents are added are studied by means of XRD. SEM etc. The results reveal that the addition of NaOH great...
