To Study the Enhancement of the Concrete Properties Prof. Prashant Kapure¹, Mr. Shreyash Kamble², Mr. Kshitij Katare³, Mr. Omkar Kharade´ ¹Lecturer, Dept. of Civil Engineering, AISSMS Polytechnic, Pune, Maharashtra, India, ²Diploma Student, Dept. of Civil Engineering, AISSMS Polytechnic, Pune, Maharashtra, India ³,⁴Diploma Student, Dept. of Civil Engineering, AISSMS Polytechnic, Pune, Maharashtra, India ---------------------------------------------------------------------***--------------------------------------------------------------------Paper 3: Jahami et al., 2024 Abstract - Concrete is a fundamental construction material, but it suffers from low tensile strength, cracking, and limited durability. Enhancing concrete properties using economical and easily available materials like fly ash, micro-silica, recycled aggregates, and fibers has gained significant research interest. This paper reviews six major research studies and their referenced literature to identify costeffective methods for improving concrete. The study focuses on cube casting experiments to evaluate compressive strength, making it practical for capstone projects and lowbudget applications.
Focused on fly ash as a partial cement replacement. Observed improved workability, durability, and gradual strength gain over 28 days. Recommended fly ash replacement of 10–15% for economical and sustainable concrete. Paper 4: Bekturganova et al., 2025 Studied polymer additives in concrete. Found that polymers improve hydration, early strength, and crack resistance, but cost and chemical handling are concerns.
Key Words: Concrete enhancement, Fly ash, Microsilica, Recycled aggregates, Fiber reinforcement, Compressive strength, Cube testing.
Paper 5: Kich et al., 2022 Analyzed fiber-reinforced concrete. Addition of polypropylene or steel fibers increases ductility and crack resistance. Strength improvement depends on fiber type and dosage (0.5–1%).
1NTRODUCTION Concrete is widely used in civil engineering due to its strength, versatility, and affordability. However, conventional concrete suffers from cracking, low tensile strength, and reduced durability. Studies show that additives like fly ash, micro-silica, fibers, and recycled aggregates can improve mechanical and durability properties. This survey reviews recent work and plans practical cube casting experiments using economical materials for strength evaluation.
Paper 6: Khan et al., 2024 Investigated hybrid fiber-reinforced concrete. Combined fibers with fly ash and micro-silica to enhance compressive and tensile strength as well as durability. Recommended combination for high-performance, low-cost concrete. Tabular Summary of Literature Review
Summary of Literature Review Paper 1: Ashokan et al., 2023 Studied the effect of nano-silica on concrete. Found that nano-silica enhances compressive and tensile strength by filling micro-pores. Concluded that 2–5% nano-silica by weight of cement gives the best performance. Paper 2: Alibeigibeni et al., 2025 Investigated recycled aggregates in concrete. Partial replacement of natural aggregates with recycled aggregates improves sustainability, though slight reduction in compressive strength occurs. Suggested 20–30% replacement is optimal.
