Analyzing Strength Properties of Self-Compacting Concrete at Elevated Temperatures

By Rahul Mewada and Harsh Rathore

Abstract: This study investigates the influence of fly ash substitution for Ordinary Portland Cement (OPC) on the compressive and splitting tensile strengths of Self-Compacting Concrete (SCC) mixes. The findings reveal that while early age strength may decrease with fly ash substitution, strategic material selection, such as incorporating foundry sand, mitigates this decline. Satisfactory fresh properties were…

Impact of Silica Fume on High-Strength Concrete

By Poonam Meshram, Shubhangi Nagrale, Anjali Gowardhan, Mitleshwar Gadwar, and Vinayak Vaidya

Abstract: For many decades, concrete has been the primary material used in construction because of itsreliability under normal conditions. However, certain applications necessitate concrete withexceptionally high compressive strength and durability, particularly in aggressive environments.Consequently, achieving compressive strengths in the range of 60–140 MPa is critical for thesedemanding situations. Silica fume, a by-product of silicon and ferrosilicon…

Optimizing Concrete Properties with Partial Replacement of River Sand by Used Foundry Sand

By Rahul Faraiya and Harsh Rathore

Abstract: In response to the scarcity and rising costs of natural river sand, researchers are exploring alternatives like Used Foundry Sand (UFS) to promote sustainable construction practices. This study investigates the partial replacement of river sand with UFS, testing replacement levels from 0% to 25% by weight. Assessing fresh concrete properties and mechanical characteristics, including compressive…

Structural Behavior of Fiber Reinforced Concrete

By Isha Ramteke, Vaishnavi Khamankar, Prerna Meshram, Tejas Deshmukh, and Nikhil Badki

Abstract: It’s a structural behavior research was done on normal concrete because it possesses low tensilestrength shows cracking. The addition of fiber can enhance the compressive and tensile properties ofconcrete. An experimental study was conducted to evaluate the compressive and tensile strength offiber-reinforced concrete, confirming the improvements in these mechanical properties. The variousaspects covered are compression…

Utilization of Waste Groundnut Shell Ash in Zero Cement Concrete

By ANUJA. N, BALAJI. A, SANJEEVI KANNAN.R, and SRINATH. S

Abstract: Currently, geopolymer concrete serves as an excellent alternative to traditional plain cementconcrete, as it is produced without using ordinary Portland cement. Different source materials suchas fly ash, rice husk ash, metakaolin, red mud etc. are preferred to act as the main source forgeopolymer production. In this work, a new innovative waste material such as groundnut…
