Around eight billion cubic metres of concrete are\u003c\/p\u003e\u003cp\u003emade each year and most of it contains dispersing admixtures.\u003c\/p\u003e\u003cp\u003eThese chemical compounds, added at low dosages during concrete\u003c\/p\u003e\u003cp\u003emixing, make fresh concrete more liquid and improve its workability.\u003c\/p\u003e\u003cp\u003eA precise way to determine the workability of concrete is to measure\u003c\/p\u003e\u003cp\u003eits rheological values yield stress and plastic viscosity. From\u003c\/p\u003e\u003cp\u003eready mixed concrete plants and concrete element plants it is known\u003c\/p\u003e\u003cp\u003ethat rheological values of mortar and concrete can sometimes vary\u003c\/p\u003e\u003cp\u003ewhen a new cement batch (i.e. a new production date) is used. The\u003c\/p\u003e\u003cp\u003eaim of this study is threefold. Firstly, to measure and evaluate the\u003c\/p\u003e\u003cp\u003eeffect of variations during routine cement production on the rheology\u003c\/p\u003e\u003cp\u003eof mortar and concrete. Secondly, to identify the constituents\u003c\/p\u003e\u003cp\u003ein cement which lead to fl uctuations in rheology. Thirdly, to quantify\u003c\/p\u003e\u003cp\u003ethe changes in rheology due to variations in cement properties.\u003c\/p\u003e\u003cp\u003eThese questions are essential for cement and concrete producers\u003c\/p\u003e\u003cp\u003eto guarantee a homogeneous concrete production, but also for the\u003c\/p\u003e\u003cp\u003escientifi c community to reach a deeper understanding of cementadmixture\u003c\/p\u003e\u003cp\u003einteractions.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783869553504\"\u003e\u003ch3\u003e\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9783869553504","offer_id":39835138654301,"sku":"9783869553504","price":48.6,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/527c6945-75fc-468c-b2c7-fcd5818c0057.jpg?v=1776487918","url":"https:\/\/shop.autorenwelt.de\/products\/interaction-of-cement-and-admixtures-and-its-influence-on-rheological-properties-von-stefan-kubens","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
