... curing, the cylindrical specimens were tested according to the ASTM C39 (ASTM, 2018a). On similar days, the compressive strengths of cube specimens were also tested by following BS 1881-116 (BS, 1983). In addition, splitting tensile of the cylindrical specimen and flexure strength of the prisms were...

... in the first mix and magnetic water was used in the second mix. A total of 48 specimens were cast and divided as follows: 16 cylinders for the concrete compressive strength test (8 samples for each mix), 16 cylinders for the splitting tensile strength (8 specimens for each mix) and 16 beams to test...

...% lime/cement ratio were studied, using three different methods to accelerate efflorescence formation. The surface area of mortars affected by efflorescence was quantified by analysis using image software. Also, analysis of mercury intrusion porosity test, flexural tensile, compressive strength...

... and has potential benefits of adding a different material to a design mix concrete mix design for improved performance. Design/methodology/approach – The test methods used to evaluate the concrete were, British Standard tests for compressive strength (BS EN 12390-3:2002) and porosity (BS EN 12390-8...

...: 100 per cent gravel replacement with recycled aggregate, and the same mix with a viscosity modifying agent. A 50 per cent partial coarse aggregate replacement was used in one batch to compare against the control and the 100 per cent recycled aggregate concrete. Compressive strength was used to compare...

... test was used to evaluate the difference between concrete made with virgin aggregates (plain control) and concrete including recycled waste. Un‐graded construction demolition waste and un‐graded ground glass were used as aggregate replacements. With regard to concrete, compressive strength is widely...

... condition and final compressive strength. A pilot study was used to determine an appropriate heat source for the test. This was three Bunsen burners, however sufficient heat could not be generated within 150 mm concrete cubes and the concrete was shown to be a significant insulator and fire protection...

...Alan E. Richardson Purpose Conflicting claims have been made in relation to the effects of polypropylene fibres on the compressive strength of concrete. The purpose of this paper is to examine the effects on compressive strength of various dosages of monofilament polypropylene fibres when used...
