Multiple studies propose the incorporation of waste glass into concrete as a sustainable solution covering many aspects, including preserving natural resources, utilizing materials and reducing cost. In present study, suitability different types flat from local industry supplementary binder or aggregate was examined. Different protocols were followed based on European American Standards. The ch...

This work aims to study the relationship between compression resistance and velocity from ultrasonic pulses in samples of mortars with 25% pozzolanic content. Pozzolanic cement is a low-priced sustainable material that can reduce costs CO2 emissions are produced manufacturing calcination calcium carbonate. Using pulse (UPV) estimate compressive content reduces when evaluating quality structures...

Hybrid Concrete focused on the development of buildings, highways, and other structures of civil engineering. In the current study, various mix combinations have been prepared and tested with different percentages of super-plasticizer at different levels of water reduction for obtaining the optimum mix. Further, study on different properties of hybrid concrete and replacement of ordinary portla...

This paper evaluated the pozzolanic activity of ceramic sanitary ware (CSW) waste when blended with Portland cement (PC). CSW units were broken, crushed and milled to reduce their particle size. These particles characterized by scanning electron microscopy (SEM-EDX), laser granulometry, X-ray fluorescence (XRF) diffraction tests (XRD), then used replace 0–50 wt.% PC CEM I 42.5R in pastes mortar...

The purpose of this research is to study the effect methods preliminary preparation thermally activated clay, which a pozzolanic component in water-resistant composite gypsum binders, as well mechanochemical activation joint grinding clay with addition plasticizer on activity and change required number composition binders. It was found that amount gypsum-cement-pozzolan when ground specific sur...

Utilization of pozzolanic materials (fly ash, slag, zeolite, metakaolin, microsilica and more) in the manufacturing of cement and concrete has increased considerably over the last decades. Another option is to use concrete containing sulfate resisting cement. This could help minimize the harmful impacts on concrete exposed to an aggressive environment. The issue of the deteriorative impact of t...

The production of cement results in emission of many green house gases in atmosphere, which are responsible for global warming. Hence, the researchers are currently focused on use of waste material having cementing properties, which can be added in concrete as partial replacement of cement, without compromising on its strength and durability, which will result in decrease of cement production t...

Hydrated lime is a historic material currently used in conservation. It hardens slowly by carbonation slowing construction however, supplementary cementitious materials accelerate hardening enhancing strength. Hydrated-lime mortars with rice husk ash–RHA-; ground granulated blastfurnace slag–GGBSand increasing amounts of two aggregates were studied. Increasing aggregate lowered strength as inte...
