It just so happened that Lawson’s company was the ideal provider for the kind of creative work the designer prefers.Price Concrete Studio has created some truly innovative pieces for that designer’s firm, including a green concrete table with brass inlays, a pink console table and more.However it is laborious and takes time to remove by vibration, and improper or inadequate vibration can lead to undetected problems later.Additionally some complex forms cannot easily be vibrated.The slump flow test allows a comparison of the lateral flow and filling potential of different SCC mixtures.A common range of slump flow for SCC is 18 to 30 in. The slump flow test can be used in production to assess the consistency of SCC.Even the architects and designers he regularly reaches out to often have no idea what types of creative challenges can be addressed with concrete.“A lot of these architects are looking for what we do, but they’re unaware that concrete can do it,” he says.

Aside from spreading understanding about the versatility of the material, the time he spends educating people is also good for his business.

SCC does not use a high proportion of water to become fluid - in fact SCC may contain less water than standard concretes.

Instead, SCC gains its fluid properties from an unusually high proportion of fine aggregate, such as sand (typically 50%), combined with superplasticizers (additives that ensure particles disperse and do not settle in the fluid mix) and viscosity-enhancing admixtures (VEA).

Concrete is a composite material composed of coarse aggregate bonded together with a fluid cement that hardens over time.

Most concretes used are lime-based concretes such as Portland cement concrete or concretes made with other hydraulic cements, such as ciment fondu.
