Abstract grass Khrhb a natural material that is readily available online by the wayside and the field as well as weeds. It makes a number of grass Khrhb increase and become a problem in storage until the present, appreciate and grass Khrhb utilized in various fields. Implementing such as animal feed, etc., as well as a research test in various fields. It tends to be a mixture of concrete because of the size of a strand of grass Khrhb look soft grip and better coordination with the binder, this research focused on the development by the hollow concrete blocks. which use agricultural materials Khrhb include a mixture of grass and conducted a study to compare the strength of the concrete blocks with the market in general to improve the properties of the concrete objective of this thesis. To study the development of concrete mixed grass Khrhb from agricultural waste. Case studies from grass fibers Khrhb Compare the ratio ratio six blocks production mix of grass Khrhb by means of compressed air compressors, hydraulic c. To study the physical properties And mechanical properties The testing of the TIS. 58-2533 test results show that the block from agricultural waste. Compressive strength of manufacturing bricks from grass fibers Khrhb the ratio 6 ratio showed that the ratio of grass fibers Khrhb the compressive strength is the ratio of the two mixture ratio is 1: 2: 8: 0.020 kg. TIS qualified. 58-2533, which sets the standards governing the testing of at least 25 ksc. This is the basis for the density standard was set at 400-900 kg / m3 Keywords: Khrhb grass fibers. , physical properties, mechanical properties.
