All specimens were cast, cured, prepared and tested in the University of Cape Town, New Engineering Building (NEB) laboratory according to South African National Standards. Twelve concrete mixes were designed using two concrete strengths (30 and 50 MPa), three maximum aggregate sizes (9.2, 19.2 and 26.5 mm) and two aggregate types, namely greywacke and quartzitic sandstone.

Mixing water is the quantity of water that comes in contact with cement, impacts slump of concrete and is used to determine the water to cementitious materials ratio (w/cm) of the concrete mixture. Strength and durability of concrete is controlled to a large extent by its w/cm.

From on-site slump testing as you pour your concrete, through to testing hardened samples for physical characteristics in our laboratories, our concrete testing includes: Sampling of fresh concrete and slump testing on site; Making and curing test specimens on your site and in our laboratory; Compression and flexural testing; Compression tests on molded specimens and on hardened concrete cores; Mass per .
In practice, concrete is initially tested for compressive strength by casting a cube/cylinder, which is left to cure in favourable conditions until the date of testing. The results obtained from such tests can give a consultant guidance on the material''s properties such as estimated porosity, density and .
A slump test is a method used to determine the consistency of concrete. The consistency, or stiffness, indicates how much water has been used in the mix. The stiffness of the concrete mix should be matched to the requirements for the finished product quality. Slump is a measurement of concrete''s workability, or fluidity. It''s an indirect measurement of concrete
