replenish the alumina soda ash values. E. The residue in limestone-predominant kerogenous ore bodies has unconverted carbon that is then calcined at over 1000° C. with requisite amount of limestone to yield a Portland cement equivalent. About 5% of the original kerogen will be unconverted carbon...
Stabilized SRS with external additives, its cost needs to be strictly controlled, with a weight value of 0.4 [38]. The weights for CBR and resilient modulus in the subgrade soil are equivalent, with both weight values of 0.3 [38]. The compaction degree of the expressway and first-grade hig...
