Prediction of Lightweight Aggregate Concrete Compressive Strength
Nowadays, the better performance of lightweight structures during earthquake has resulted in using lightweight concrete more than ever. However, determining the compressive strength of concrete used in these structures during their service through a none-destructive test is a popular and useful method. One of the main methods of non-destructive testing in the assessment of compressive strength...
متن کاملProperties of lightweight aggregate produced by rapid sintering of incinerator bottom ash
The fraction of municipal solid waste incinerator bottom ash with a particle size less than 8mm has been milled, formed into pellets and rapidly sintered in a rotary furnace at temperatures between 900 and 1080 ◦C. The effect of sintering temperature on density, water absorption and crushing strength has been determined. Sintering at temperatures between 1000 and 1050 ◦C produces pellets with p...
متن کاملFuzzy Logic Model for Prediction of Compressive Strength of Lightweight Concrete Made with Scoria Aggregate and Fly Ash
In this study, a fuzzy logic prediction model for 3, 7, 14 and 28 days compressive strength of lightweight concrete made with scoria aggregate and fly ash under different curing conditions (standard and air curing) was devised. In mixtures containing fly ash, 15% of Portland cement by weight was replaced with fly ash. The specimens were cured in standard curing conditions at temperature 20±2 °C...
متن کاملThermal Behaviour of Metakaolin/Fly Ash Geopolymers with Chamotte Aggregate
Geopolymers are generally appreciated for their good resistance against high temperatures. This paper compares the influence of thermal treatment with temperatures ranging from 200 to 1200 °C on the mechanical properties and microstructure of geopolymers based on two different aluminosilicate precursors, metakaolin and fly ash. Moreover, the paper is also aimed at characterizing the effect of c...
متن کاملProperties of Green Lightweight Aggregate Concrete
With increasing concern over the excessive exploitation of natural aggregates, synthetic lightweight aggregate produced from environmental waste is a viable new source of structural aggregate material. The uses of structural grade lightweight concrete reduce considerably the self-load of a structure and permit larger precast units to be handled. In this paper, the mechanical properties of a str...
