·Fiber reinforced recycled aggregate concrete FR RAC has recently gained more popularity because of its advantages high strength eco friendliness and cost effectiveness This study uses an advanced machine learning technique for forecasting the compressive strength of FR RAC In this study an experimental database that contained pertinent data from
·Uniaxial compressive strength UCS which is one of the most important engineering properties of natural building blocks exhibits a decrease at various rates under the effect of freeze thaw FT cycles In this study practical estimation of UCS loss of 21 groups of carbonate building stones exposed to 4 7 10 14 20 28 35 56 70 and 84 FT cycles is aimed
This paper deals with an experimental investigation on the strength of stone and stone masonry Granitoidgneiss is commonly used for masonry construction in India The compressive strength of stone has been determined through 80 mm size cubes It has been found that the compressive strength of granitoid gneiss is greater when the load is parallel to the mineral bands The
3 ·The two factors that are important for natural stone veneer are compressive strength and water absorption More than 90% of all volcanic rock on Earth is basalt Basalt stone lines most of the ocean floors and is one of the most common stone types on the moon Basalt was used for building projects in ancient Rome the Rosetta stone is made
·Mt Eden basalt and Port Hills basalt had a comparable compressive strength and were collected from A1 f The compressive strength of natural stones was identified to be greatly influenced by the extraction site crystal grain size mineral composition and for the type of stone considered less influenced by the bedding planes and foliation
·Based on this basalt powder BP fly ash FA and slag powder BF were used as supplement cementitious materials in this paper Firstly the response surface central composite design method RSM BBD was used to study the influence of stone powder composite cementitious materials on strength at different ages and the strength response surface
·Compressive strength The compressive load required to cause failure of an unconfined cylindrical or cubical specimen of the stone divided by the cross sectional listed in the Natural Stone Directory do not give quan titative data for their stones Table C1 shows that with the exception of bulk density physical and strength
·[19] investigated the compressive strength of NaOH activated basalt systems by varying the activator dosages and curing temperatures They determined that a moderate compressive strength about 16 MPa can be realized and the compressive strength can be improved by increasing the curing temperature and they
