In Japan, coal-fired power is one of the main electric powers along with atomic power and natural gas -fired power. The annual amount of coal used for coal-fired power ge [...]

Current loads from cement production make material responsible for 5-7% of CO2 emissions with more than 2x109 ton of CO2 emitted. Considering available industrial product [...]

This study investigates performance of slag as an alternative cementitious binder against ordinary Portland cement (OPC), fly ash (FA) and palm oil fuel ash (POFA). To ac [...]

By calcination and dehydration of paper sludge, which is a by-product of recycled paper waste, a non toxic mineral with a highly pozzolanic activity is formed. Besides th [...]

In this paper, effect of cement type and expansive additive content on resistance to both drying shrinkage cracking and thermal cracking of concrete using fly ash and gro [...]

Recently, blended cement is needed in order to lower the energy consumption and CO 2 emission from cement industries. On the other hand, waste management and environmenta [...]

Low calcium fly ash-based geopolymer (LCFG) concrete binder, which results from the reaction of a source material rich in silica & alumina (low calcium fly ash) and a [...]

There are many ways to reduce the carbon footprint of concrete including reduction in its Portland cement clinker content by methods including: (a) optimization of total [...]

The present paper is directed towards development of statistical models for the evaluation of efficiency factors of fly ash so that its contribution on concrete strength [...]

The study aims at using Shirasu, which is a pyroclastic flow deposit like volcanic ash, as one of the binders in mortar or concrete. It is one of the unused natural resou [...]

The development of innovative eco-efficient cementitious materials is, nowadays, a wide-spread concern to assure the sustainability of the built environment. In this scop [...]

The main results of a large research project undertaken in order to validate the composition of new ternary cements containing Portland clinker, limestone filler and slag [...]

In order to reduce the amount of CO2 gas in cement industry, the use of blended cement is valid. Share of blended cement in Japan, has not changed over last 10 years. One [...]

Porous ceramic aggregate produced from roof tile waste was used as an internal curing agent. The aim of this study is to investigate the effect of the porous ceramic aggr [...]

An experimental investigation was conducted to study both the mechanical and durability performance of various specimens constructed with both high-volume fly ash concret [...]

An experimental investigation was conducted to study the shear strength of full-scale beams constructed with both high-volume fly ash concrete (HVFAC) – concrete with a [...]

In this study, optimum combinations of the replacement ratios of fly ash (FA) and ground granulated blast-furnace slag (BS) with cement were examined from the aspect of p [...]

In order to reduce environmental loading, it is important to propose the way for the usage of large particles of Fly Ash. In this research, relationship between packing f [...]

This paper reports the potential reuse of incineration fly ash (IFA) as cement supplements in the production of engineered cementitious composites (ECC), a unique class o [...]

This study investigated the performance of two high-volume fly ash concrete (HVFAC) mixes with 70% replacement of Portland cement with a Class C fly ash (with one mix hav [...]

The major environmental impact of concrete is caused by CO2-emissions during the cement production. Great potential for the reduction of the global warming potential and [...]

Due to incentives to reduce greenhouse gas emissions during clinker production more and more of the clinker fraction of cement is being replaced with supplementary cement [...]
