Abstract Concrete with high ductility, workable, strength, easy to flow without compaction, and durable is a concrete need in the future. this quality, one of which make self-compacting (SCC). This paper reports performance self compacting (SCC) containing rice hush ash. Rice husk ash waste from burning husks. The purpose study was determine SCC addition specimens were made using (RHA) (NRHA). ...

Rice is the second most extensively consumed food ingredient, and its by-products in paddy field include rice husk straw. ash, resulting from burning, considered an environment menace, inducing negative effects on area which it disposed of. In this study, was applied as a silicate source to obtain mesoporous silica material. Characterization techniques confirmed well-ordered mesophase resemblan...

Abstract Application of different forms silicon sources may influence rice production and quality. It is believed that properties nanosized particles differ significantly from those the original bulk material. This study aimed to investigate effects application silica nanoparticles extracted husk ash, called nanobiosilica (NBS), on growth, productivity, milling quality as compared ash (RHA), so...

The influence of crop residue amendments on the chemical properties of an acid soil and rice yields was investigated at Abakaliki for two cropping growing seasons (2006 and 2007). The residue treatments were rice straw, burnt rice husk and legume residue, while the rice cultivars were ITA 315, Ex-China and ITA 257. The design of the experiment was a 3 x 4 factorial in a Randomize Complete Block...

The early age shrinkage is responsible for the early age cracking of concrete. It is very critical for durability of concrete. The change in volume of concrete due to evaporation of water or dehydration process is known as shrinkage. To reduce the early age shrinkage utilized the supplementary cementitious material (SCM) in concrete. In present research industrial and agricultural waste byprodu...
