Mixes with 20% and 40% cement  replacement with RHA (the latter contained a WR)  were selected for further testing. These tests  included shrinkage, tensile strength, permeability  and carbonation. Mixes with added lime were produced  for the permeability and carbonation tests. Due to  the encouraging results further concrete mixes for  compression testing were produced that contained  additional lime. Bleeding tests were also carried  out on selected mix designs.HSC mixes containing RHA  and Condensed Silica Fume (CSF) were investigated.  The effect of RHA on a superplasticiser was  examined. The temperature profiles of mixes  containing RHA with a design strength of 50 MPa were  monitored. Generally, the performance of RHA in 25  MPa and HSC has been assessed with conclusions made  on the potential of this product in the construction  industry.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783838352015\"\u003e\u003ch3\u003eThe use of rice husk ash as a pozzolanic admixture in concrete\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9783838352015","offer_id":39499043340381,"sku":"9783838352015","price":68.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/cd5bbd28-bbaf-4736-ab4c-aad55389dc51.jpg?v=1775627502","url":"https:\/\/shop.autorenwelt.de\/en\/products\/rice-husk-ash-in-concrete-von-marc-smajila","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
