{"product_id":"rice-husk-ash-von-eng-agus-setyo-muntohar","title":"Rice Husk Ash","description":"\u003cp\u003eRice husks are major agricultural by-product obtained  from the food crop of paddy. Generally, it is  considered a valueless product of rice milling  process. Chemical analyses have shown that the ash  i.e. rice husk ash (RHA), is a highly reactive  pozzolanic material. RHA contains a high amount of  silica dioxide suitable for use in lime pozzolana  mixes and Portland cement replacement. On this ground  the contribution of rice husk ash to the engineering  application needs further investigation. This  research concerned with the effect of the adding RHA  to lime-treated expansive soil on its engineering  properties. This includes the study on the swelling  behaviour of untreated and treated specimens.  Experimental soils are prepared by mixing  commercially available clay minerals with sand in  different proportions to obtain a wide variety of  soil characteristics. The basic clay minerals used  are bentonite and kaolinite. A series of laboratory  work is conducted to study the change in of physical  and geotechnical properties of expansive soils,  including durability and serviceability. A mixture  design and testing procedure for lime-RHA treated  soils are established as outcome of this research.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783844385014\"\u003e\u003ch3\u003eEnhanced Lime-Stabilised Expansive Soils\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9783844385014","offer_id":39493525930077,"sku":"9783844385014","price":49.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/422b85d1-47d0-44d2-9a47-bf4a24db55d0.jpg?v=1769494228","url":"https:\/\/shop.autorenwelt.de\/en\/products\/rice-husk-ash-von-eng-agus-setyo-muntohar","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
