During this study, Class C Fly Ash, and its composites with sand were fabricated at different compaction stresses by maintaining a low w/c (w-water, c-cement) ratio of 0.17鈥 0.24 in the compacts. The porosity and curing time played a significant role in the evolution of compressive ...
The effect of incorporating high volume of Class C fly ash (FA) on mechanical properties of autoclaved SIFCON (slurry infiltrated fiber concrete) has been investigated in this study. Cement was replaced with up to 60% FA in SIFCON compositions and three different steel fiber volumes (2%, 6% ...

Evaluation of the anterior crossbite aimed to differentiate a true Class III malocclusion from a pseudo Class III maloc- clusion has been described by Ngan et al,60,65 and the given diagnostic scheme can be adapted (Figure 1). Lateral cephalogram analysis Best analyses for cephalometric ...
The compressive strength of geopolymer prepared from a class C fly ash (CFA) at different curing conditions and mass ratio of water to fly ash were investigated. The geopolymer was activated with a mixed solution of sodium hydroxide (NaOH) and sodium silicate. The results revealed that the obta...

The compatible-gene hypothesis was supported by the result that true mating pairs had higher pairwise amino-acid distance (Fig. 2a) and amino-acid function distance (Fig. 2c) MHC class I diversity predicts non-random mating in Chinese alligators (Alligator sinensis) 815 Fig. 3 Effect of ...
, in which the four oxygen atom is attached to one silicon atom. when silicate unit is joined together it forms ring, chain as well as 3-d structure. glass and cement are two important silicates that are man-made. zeolites aluminosilicate is formed when in the three-dimensional structure ...
