Sand Equivalent Value

2009/6/30In our Specification there is a requirement which says, 'the aggregate shall meet the sand equivalent (clay content)requirements minimum sand equivalent percent 40 '. If we see the sand equivalent formula, which is 100*sand reading/ clay reading, the higher the sand reading during testing means it gives higher sand equivalent value, and that means there are less clayey materials.Get price

Subgrades Subbases for Concrete Slabs

2018/7/31Concrete strength also comes into play, but most slab concrete is around 3000 to 4000 psi, so it's not a major factor. The tensile strength of concrete is typically taken as 10 to 15% of the compressive strength, so only about 400 or 500 psi.Get price

REQUIREMENTS FOR CONCRETE MIX DESIGN

Requirements of concrete mix design should be known before calculations for concrete mix. Mix design is done in the laboratory and samples from each mix designed is tested for confirmation of result. But before the mix design process is started, the information about available materials, strength of concrete required, workability, site conditions etc. are required []Get price
