{"product_id":"otrec-rr-11-09","title":"OTREC-RR-11-09","description":"\u003cp\u003eThe primary goal of this research project was to investigate the long-term durability of concrete incorporating\u003cbr\u003e\nrecycled concrete aggregate (RCA) through accelerated laboratory testing. Overall it was found that modifications to\u003cbr\u003e\nstandard aggregate testing and characterization standards were necessary for testing RCA. This included\u003cbr\u003e\nmodifications to standard tests including ASTM C 128, C 305 and C 1260. It was found that the potential for alkalisilica\u003cbr\u003e\nreactivity did exist for new concrete containing RCA. The characteristics of the RCA also had a profound\u003cbr\u003e\neffect on ASR related expansion. RCA with a higher content of reactive coarse or fine aggregate (compared to paste\u003cbr\u003e\nfraction) exhibited greater reaction and would therefore require higher levels of mitigation. Based on testing in this\u003cbr\u003e\nresearch project precision and bias statements in ASTM C 1260 (for virgin aggregate) do not apply to RCA.\u003cbr\u003e\nRecommendations for future work are also included in this report.\u003c\/p\u003e","brand":"Jason Ideker","offers":[{"title":"Paperback","offer_id":44310484582561,"sku":"9781111128231","price":23.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0462\/1120\/3233\/files\/1dmm2777-front-shortedge-384_f3b00776-f7fb-4112-ac33-049ac94f4d02.jpg?v=1748404494","url":"https:\/\/bookswholesale.myshopify.com\/products\/otrec-rr-11-09","provider":"BooksWholesale","version":"1.0","type":"link"}
