concrete and unreinforced masonry walls: prediction, test results and data set ... Abstract This paper presents the results of a series of shaketable tests on a halfscale, fourstorey building with reinforced concrete and unreinforced masonry walls. Due to the lack of reference tests, the seismic behaviour of such mixed structures is poorly ...

Carbonation of concrete However, it also increases both the compressive and tensile strength of concrete, so not all of its effects on concrete are bad. Carbonation is the result of the dissolution of CO 2 in the concrete pore fluid and this reacts with calcium from calcium hydroxide and calcium silicate hydrate to form calcite (CaCO 3 ).

The mortar used in this research was tested for compressive and flexural strengths as per the provisions in BS EN 1961:2005. The Australian Masonry standard does not provide any mechanical testing for masonry mortar. The compressive strength of the mortar was determined from cylindrical specimens of 50 mm diameter and 100 mm high.
BS EN 123502:2009 Testing fresh concrete. Slumptest. BS EN 123502 specifies a method for determining the consistence of fresh concrete by the slump test.

Sustainable reinforced masonry walls under lateral inplane load: Experimental behavior and codebased predictions ... eight near fullscale squat walls of 150 mm and 100 mm thick hollow unit clay and concrete masonry units were tested to failure under monotonic inplane lateral load. The vertical reinforcement was selected to comply with the ...
Abstract. Hollow concrete block masonry is widely in use. In this study hollow blocks are tested for their compressive strength. The overall lateral strength of masonry walls made of hollow concrete blocks is compared with the lateral strength of the firebrick kilned masonry wall.

Procedure for site testing construction fixings 2012 PROCEDURE FOR SITE TESTING CONSTRUCTION FIXINGS –2012 (07 12 12) 3 2 SCOPE BS 8539 outlines the test regimes (number of tests, test load, assessment of results) which need to be satisfied to achieve the appropriate objectives. These are summarised below.
The 'concrete cube test' is the most familiar test and is used as the standard method of measuring compressive strength for quality control purposes. Concrete beam specimens are cast to test for flexural strength and cast cylinders can be used for tensile strength.
