    use an edging trowel around the entire perimeter of the concrete which will also compact the edges of the concrete. for larger slabs, use a jointing trowel to provide control joints at 150cm intervals, by creating a straight groove around 2cm deep in the slab. the inclusion of control joints will control cracking.

    How Proper Prep Leads To Crack-Free Concrete

    a good base is everything! concrete will crack and crumble if it’s not poured over a solid, stable base. bringing in 4 to 6-in. of a good compact-able base is a good rule of thumb, but the exact amount of base a concrete driveway needs depends on the condition of the existing soil, the climate, and what you plan to park on your driveway.

    the proper way to build a driveway is to excavate (depending on design load) from 1-3 feet down (generally about 12-18') depending on what your existing soil conditions are, place a structural geotextile if still poor (soft or muddy or clayey) conditions at that depth, then place and compact subbase material (which may be a crushed rock or a gravel, free-draining, typically 2' minus) up to

  • Rammed earth | YourHome

    Rammed Earth | YourHome

    rammed earth walls are constructed by ramming a mixture of selected aggregates, including gravel, sand, silt and a small amount of clay, into place between flat panels called formwork. traditional technology repeatedly rammed the end of a wooden pole into the earth mixture to compress it. modern technology replaces the pole with a mechanical ram.

    concrete 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. compare that to the tensile strength of grade 60 rebar, which is 60,000 psi.
