The Compressive Strength Development of Briquette Ash by Alkali Activated Reaction

the effect of taftan pozzolan on the compressive strength of concrete in the environmental conditions of oman sea (chabahar port)

cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...

PROPERTIES OF ALKALI-ACTIVATED FLY ASH CONCRETE BLENDED WITH SLAG

The Promotion of Nano-SiO2 on the Compressive Strength of Alkali-Activated Materials

Nanomaterial which has high activity is widely used in the modification of cement-based materials due to its physical filling and chemical bonding. This paper mainly studied the influence of nano-SiO2 on the compressive strength of the alkali-activated materials, using XRD and SEM technology to analyze the mineral composition microstructure of alkali-activated materials, modification effect, et...

ALKALI Activated FLY-ASH Based Geopolymer Concrete

Considering the increasing demand for developing alternative construction materials, due to the growing environmental concerns, this paper discusses the feasibility of alkali activated geo-polymer concrete, as a future construction material. The main objective of this study involves observation of structural behaviours of the fresh fly ash-based geo-polymer concrete, understanding the basic mix...

Strength and Durability Performance of Alkali-Activated Rice Husk Ash Geopolymer Mortar

This paper describes the experimental investigation carried out to develop the geopolymer concrete based on alkali-activated rice husk ash (RHA) by sodium hydroxide with sodium silicate. Effect on method of curing and concentration of NaOH on compressive strength as well as the optimum mix proportion of geopolymer mortar was investigated. It is possible to achieve compressive strengths of 31 N/...
