Rice husk ash concrete and preparation method thereof

Abstract

The invention discloses rice husk ash concrete and a preparation method thereof. The rice husk ash concrete is prepared from, by weight, 284-369 parts of cement, 21-64 parts of rice husk ash, 21-64 parts of fly ash, 12.7 parts of silica fume, 503.5 parts of sands, 977.4 parts of pebbles, 2 parts of water reducer and 195 parts of water; the unit of weight proportioning is kg / m<3>.

Description

technical field [0001] The invention belongs to the technical field of inorganic non-metallic materials, and in particular relates to a rice husk ash concrete and a preparation method thereof. Background technique [0002] Concrete, the most widely used building material in the world, its development dates back to a very ancient time and has been developed and expanded to this day. It is reported that as early as thousands of years ago, Chinese ancestors used the construction technology of "digging grooves to fill and burn soil, and wooden bones to support mud walls" to build houses. According to archaeologists, the Lingjiatan people at that time used wooden sticks, burned soil, clay, and even reeds to reinforce their houses. Concrete is very similar in the process of making it. This may be the earliest mastery and application of concrete by ancient Chinese. The pyramid, one of the eight wonders of the ancient world built in Egypt in 3000 BC, is said to have been built by...

Problems solved by technology

However, the massive use of silica fume and the accompanying problems are also very acute: the cost of obtaining silica fume as a concrete admixture is very high, the transportation is difficult, and the consumption of electric energy is also very large.

This has resulted in many small enterprises not having enough capital to use silica fume to make high-performance concrete, and the cost of high-performance concrete made of silica fume is relatively high
