EFFECT OF EXPOSURE OF CEMENT ON THE COMPRESSIVE STENGTH OF CONCRETE
Abstract: Concrete has become the bedrock of infrastructural civilization in Nigeria as over 75% of the infrastructures in Nigeria have to do with concrete. Most times, Engineers design for a particular grade of concrete and Post-construction checks shows that concrete is defective of this strength and exposure of cement is observed to be one of the causative factors. In this study, the effect of exposure of cement on the compressive strength …

Enhancing Strength and Durability: A Study of Mortar Blocks with Steel Slag Incorporation and the Development of Steel Slag Lime and Cement Blocks
Abstract: This study is focused on investigating the strength and durability properties of mortar cubes made with slag cement and incorporating Ultra Fine Steel Slag (SS) as a potential replacement for natural fine aggregates (FNA). In some instances, the cement was entirely replaced with hydrated lime to develop the blocks. A battery of tests, including assessments of compressive strength, acid resistance, sulfate resistance, water absorption, and void analysis, were carried out …

Durability Assessment of Geopolymer and OPC Concretes under Chloride and Sulphate Chemical Attack
Abstract: The main problems with durable concrete constructions are attacks by sulphates and chlorides on concrete. The primary objective of this study is to evaluate how the strength properties of concrete are affected by the incorporation of fly ash when exposed to environmental conditions involving sulphate and chloride solutions. In this research, geopolymer concrete (GPC) is utilized as a replacement for conventional ordinary Portland cement (OPC). The concrete composition is prepared …

A Study on Strength and Durability of Fly Ash–Metakaolin Blended Geopolymer Concrete
Abstract: Production of cement causes 8% of the total carbon dioxide emissions in the world. Finding a right alternative to cement is the need of the hour, to eliminate environmental pollution caused by cement production. A substitute for conventional concrete can be industrial waste products like GGBS, Flyash, Metakaolin, and so on, these mineral admixtures can be used to fully replace cement with some activators this mix of mineral admixtures and …

Service Life Prediction of Concretes Incorporated with Fly Ash and Alccofine with respect to Chloride Ion Penetration
Abstract: Chloride-induced corrosion poses a significant threat to the degradation of reinforced concrete structures, especially in extreme environments such as marine and industrial exposure conditions, where the damage can be particularly severe. This study provides an experimental investigation utilizing three distinct water-binder ratios (0.3, 0.4, and 0.5) applied to three types of concrete mixtures: conventional concrete, concrete blended with 40% fly ash, and concrete blended with 40% fly ash and 2% …

COMPARATIVE STUDY OF COMPRESSIVE AND FLEXURAL STRENGTH OF CONCRETE BY PARTIAL REPLACEMENT OF CEMENT BY NANO SILICA POWDER IN M40 GRADE CONCRETE
Abstract: Concrete, a fundamental building material, traditionally relies on cement as a primary binder. However, the environmental and economic challenges associated with cement production have driven the search for alternative materials that can partially replace cement while maintaining or enhancing concrete's performance. This study focuses on the effects of Nano Silica Powder as a partial substitute for cement in M40 grade concrete, an advanced solution aimed at reducing the carbon footprint …

Performance of Plastic-Coated Aggregates Along with Epoxy Resin in Aggressive Environment
Abstract: Construction and demolition activities are increasing rapidly therefore concrete recycling has gained importance which has not only limited the use of natural resources but also eliminated the need of disposal sites thereby saving the land and environment. These recycled aggregates from concrete recycling are being used in various constructions works like in buildings, pavements etc. In the present work natural coarse aggregates have been partially replaced with recycled coarse aggregates …

Development and Characterization of Bottom Ash–Fly Ash–GGBS-Based Geopolymer Composites for Sustainable Applications
Abstract: The growing demand for sustainable construction materials has spotlighted geopolymer concrete (GPC) as an environmentally viable substitute for conventional cement-based systems. This study presents an innovative dual-waste valorization approach, integrating pulverized bottom ash (BA) and ground granulated blast furnace slag (GGBS) as binders while replacing sodium silicate (Na₂SiO₃) in the alkaline activator with treated textile effluent. Unlike prior works that focus solely on solid waste incorporation, this research pioneers the …
