    PERFORMANCE STUDY OF LOCALLY AVAILABLE COARSE AGGREGATES

    Mar 31, 2013 Lawrencepur sand was used as fine aggregates in all compositions of concrete. Different coarse aggregates used to make concrete were Hajira, Kamser, Arja, Sargodha and Marghallah. Maximum size of coarse aggregate used in concrete was 19mm. Water cement ratio for all concrete mixes was kept as 0.55. Composition of the concrete is given in Table 1

    Sep 14, 2020 Crushing strength of sand grains and rock aggregates has been studied by several authors based on numerical and experimental works using compression between parallel stiff platens or point load tests [36, 39, 45].Several authors have proposed expressions to obtain the tensile strength induced by compressive loading, showing that the stress state inside a particle depends on the

    Mechanical behavior of three generations of 100%

    Aug 29, 2014 Natural coarse aggregate’s absorption capacity was only 1.2%, which was much lower than any of the recycled aggregates. The high absorption values of repeated recycled coarse aggregate appear mostly due to the presence of the residue of cement paste that still remained on the surface of the parent coarse aggregate after crushing

    Provides strength. The aggregates are used as an important ingredient in the preparation of concrete. The fine aggregates are used in concrete as a filler material, and the coarse aggregates give the compressive strength to the concrete. When we estimate the concrete quantity, the aggregates will occupy 70 to 75% of the volume

    Jul 05, 2018 Shape and texture of aggregate. Smooth and rounded aggregates are easy to mix and more workable, and aggregates obtained by crushing stones produce a higher surface-to-volume ratio, better bond characteristics, and better strength. However, the crushed aggregates require a higher amount of cement paste to make the mixture workable

    Dec 19, 2019 The aggregate crushing value test indicates the strength of aggregate which is the most essential property of coarse aggregate. The aggregate crushing value provides a relative measure of resistance to crushing under a gradually applied compressive load. For achieving a high quality of pavement, aggregate of higher crushing strength i.e. low

    Experimental study on lightweight concrete using pumice

    Jan 01, 2021 Pumice aggregate absorbs more water as compared to normal coarse aggregate because pumice aggregate contains more pores hence strength will be reduced. Hence superplasticizers are used [7] . The compressive strength, split tensile strength and flexural strength of Pumice LWAC with 50%, 80% and 100% replacement shows that only 50% replacement
