Methods of wellbore cementing are provided. A method of cementing may comprise: calculating a lime to silica correlation for two or more cementitious components of a cement composition; and adjusting a concentration of at least one of the cementitious components such that the lime to silica correlation meets or exceeds a target.

A synergistic disposal method of hazardous waste incineration residues and solid wastes, ceramsite and an application thereof, all belonging to the field of resources and environment. The disposal method includes the following steps: mixing of the hazardous waste incineration residues and solid wastes, granulation and dehydration of the resulting mixture and calcination to obtain ceramsite. In the preparation of ceramsite by the synergistic disposal of hazardous waste incineration residues and solid wastes as the raw materials, dioxin and organic matters in the hazardous waste incineration residues and solid wastes are decomposed, meanwhile the contained heavy metals are reduced and solidified, solving the disposal problem of hazardous waste incineration residues and solid wastes, saving a lot of land for landfills, decreasing the cost for comprehensive disposal, not producing new hazardous wastes, and reducing the burden of ecological environment.
