The Use of Rice Husk Waste in Foam Concrete Production

Abstract

It is stated that concrete, which is the basic building block of most of the buildings built today, is themost consumed the construction material in the world after water. cement is that is the main ingredientof concrete, has significant share because of the cost of concrete, the use of various additives as acement substitutes is the subject of many studies. However, it should firstly be determined to whatextent the additives used to affect the concrete properties. In this study, it was tried to determine towhat at level the use of the ash of rice husk as a cement substitute changed some concrete properties.Within the scope of the study, the usability of the raw form of rice husk as aggregate in concrete wasevaluated and thus an effective method in the disposal of rice husk, which is a agricultural waste, wastried to be determined. The study results show that the addition of both ash of rice husk and rice huskaggregate significantly alter almost all properties of concrete. These changes are at different levelsfor different characteristics. As a result of the study, it was determined that as the amount of foamincreased, the flow diameter increased, while the addition of rice husk decreased the flow diameter.It was determined that the addition of rice husk decreases the depth of water penetration dependingon time, the porosity of the samples with the high level of rice husk addition increases, and thecompressive and flexural strength decreases.
