The industrial production of lime generates greenhouse gases, which contributes to increase the global warming. Therefore, present study evaluated feasibility replacing by ornamental rock waste (ORW) as a by-product related stone industry, and developed cost-effective mortars. These new low-costing mortars are intended fresh fluid paste coatings be applied on walls mechanized projection techniq...

The possibility of using ferritic clinker as a component binders with special performance properties is considered. Such types cements can solve the problems providing construction industry high-strength, resistant to external aggressive effects and relatively cheap binders. However, mechanism hardening curing cement stone obtained by clinkers complicated depends on number parameters.

Abstract Japan is located in the international seismic zone, and also a resource intensive country. It has unique features research application of ultra-high performance concrete materials. The paper analyzes summarizes engineering cases strength grade above 150 N/mm 2 , including structural system, mix design, production process, grade, etc. Silica fume composite cement, with strict calculatio...

This research investigated the optimization of locally sourced aggregate, mixed with variable cement ratios to determine its optimum compressive strength. Samples standard sizes local fine and coarse aggregate were obtained at popular excavation sites. The concrete materials weighed, batched, mixed, cast cured using four different mix proportions 1:2:4, 1.2:2:4, 1.4:2:4 1.6:2:4 cement, constant...

Objective: The development of a Self-Compacting Concrete (SCC) mixture requires different composition compared to normal vibrated concrete. This experimental study was designed propose modification the concrete mix design formula produce an SCC that meets specified requirements for both fresh and hardened using Ground Calcium Carbonate (GCC) as local fine powder material. Methods: research carr...

It is difficult to support roadway with anchor cable in view of impact tendency impinging liability roadway; a new material inorganic and high-performance full-length anchoring for developed by adding several modifiers ultrafine cement as the main material. The purpose improve mechanical properties durability cement-based materials, coordination system, ensure stability surrounding rock mining ...
