Factors Influencing Compressive Strength of Geopolymer Concrete
To study effects of several factors on the properties of fly ash based geopolymer concrete on the compressive strength and also the cost comparison with the normal concrete. The test variables were molarities of sodium hydroxide(NaOH) 8M,14M and 16M, ratio of NaOH to sodium silicate (Na2SiO3) 1, 1.5, 2 and 2.5, alkaline liquid to fly ash ratio 0.35 and 0.40 and replacement of water in Na2SiO3 s...
متن کاملCompressive Strength and Workability Characteristics of Low-Calcium Fly ash-based Self-Compacting Geopolymer Concrete
Due to growing environmental concerns of the cement industry, alternative cement technologies have become an area of increasing interest. It is now believed that new binders are indispensable for enhanced environmental and durability performance. Self-compacting Geopolymer concrete is an innovative method and improved way of concreting operation that does not require vibration for placing it an...
متن کاملThe Pore Characteristics of Geopolymer Foam Concrete and Their Impact on the Compressive Strength and Modulus
The pore characteristics of geopolymer foam concretes (GFCs) manufactured in the laboratory with 0–16% foam additions were examined using image analysis (IA) and vacuum water saturation techniques. The pore size distribution, pore shape, and porosity were obtained. The IA method provides a suitable approach to obtain the information of large pores, which are more important in affecting the comp...
متن کاملEffects of Nano-SiO2 on Setting Time and Compressive Strength of Alkali- activated Metakaolin-based Geopolymer
This study presents a discussion on the effects of different solid-to-liquid (S/L) ratios (0.97 to 1.19) and nanoSiO2 (NS) percentages (0% to 3%) on some properties of metakaolin (MK)-based geopolymers. The setting time and compressive strength were investigated. Mercury intrusion porosimetry, fourier transform infrared spectroscopy, and scanning electron microscopy were used to determine the m...
متن کاملEffect of Synthesis Parameters on the Compressive Strength of Fly Ash Based Geopolymer Concrete
The paper presents the effect of different synthesis parameters, such as (a) fly ash to alkaline solution ratio, (b) concentration of NaOH solution, (c) concentration of sodium silicate solution, (d) geopolymer solids to water ratio and (e) sodium silicate to sodium hydroxide solution ratio, on the compressive strength of geopolymer concrete synthesized from fly ash of Indian origin. It is obse...
