The world production of cement in 2007 was about 2.6  billion tons, compared to just 10 million tons  in 1990. Traditionally, concrete was understood as a  mixture of cement, water and aggregate but in modern  concrete other constituents may also be present such  as mineral components, chemical admixtures and  fibres. Normal and high strength concretes were  developed in the early 1900''s and 1950''s,  respectively, whereas the development of ultra-high- performance concrete known as reactive powder  concrete (RPC) was originated in the mid 1990''s. RPC is an ultra-high strength cementitious material that contains a high quantity of cement and silica fume, low quantity of water, incorporates large amounts of fibres and exhibits remarkable ductility, durability and strength properties. In this book, the mechanical behaviour of steel fibre reinforced RPC girders is detailed and design models presented. Particular emphasis is placed on non-flexural actions such as shear and bursting where steel fibres are used to replace conventional steel reinforcing bars.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783838324067\"\u003e\u003ch3\u003eAnalysis and Design of RPC Girders\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9783838324067","offer_id":39498895196253,"sku":"9783838324067","price":79.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/8401d4e7-9168-4226-9158-d325e8146f1b.jpg?v=1771310081","url":"https:\/\/shop.autorenwelt.de\/products\/reactive-powder-concrete-von-yen-lei-voo-und-stephen-foster","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
