Steel Roofing Structural systems are those, such as SSR, that are installed directly on the roof structural system (i.e., purlins), without decking. These are low slope systems, up to about 1:12 pitch, using bare, heavier gauge GALVALUME steel sheet. Use in this application is guaranteed for 20 years.

The Difference between Concrete and Screed The basic chemistry is the same for both concrete and screed – the cement and water forms a paste and coats the surface of the sand or the aggregates, and the cement paste hardens by a process called hydration, forming a hardened mass of high strength and durability.n contrast, screed is used to create a smooth level surface for the final finish, and is not intended to be used as a final wearing surface. But screeds should be able to provide sufficient support and strength to withstand the traffic under its intended use.

The Snippet Seamstress Helicoidal flow is a cockscrew (spiral) movement of water responsible for moving eroded river load from the outer bank and then depositing much of it on the next inner bank of a river. Posted by Snippetseamstress at 8:33 AM 41 comments: Labels: bottom or subsidiary current, helicoidal flow, top current.t is associated with the presence of pools and riffles in the river bed. The erosion and deposition of river load by helicoidal flow is responsible for the creation of meanders. The top current hits against the river bank, undercutting and eroding material from it.

- Traditionally, screed is laid around 75mm thick onto a concrete subfloor. It’s a skilled job, usually undertaken by plasterers when the walls and ceiling are plastered. A screed mix is relatively strong, using one part cement to three parts sharp sand, and when done well it gives a smooth and level floor on which to lay your chosen floor finish. A screed is also the preferred medium when laying underfloor heating pipes. You do not have to use a screed.

The Difference between Concrete and Screed Composition and Mix Proportion. Concrete in its simplest form is a rock like mass formed by the hardening of cement paste and aggregates mixed in a proportion of – 1Cement: 2Sand: 3Coarse aggregates (ballast/gravel).But several variations are applied to this basic mix design to suit various uses and strength requirements.oncrete in its simplest form is a rock like mass formed by the hardening of cement paste and aggregates mixed in a proportion of – 1Cement: 2Sand: 3Coarse aggregates (ballast/gravel).

Craton A craton’s most characteristic structural feature is its two structural stages. The basement is the lower and more ancient stage and is composed of intensely dislocated metamorphosed and granitized rocks; it represents a formation of the precratonic, or geosynclinal, developmental stage of the earth’s crust.

- Curtain grouting is the construction of a curtain or barrier of grout by drilling and grouting a linear sequence of holes. Its purpose is to reduce permeability. It may cross a valley as a vertical or an inclined seepage cut-off under a dam; it may be circular around a shaft or other deep excavation; or it may be nearly horizontal to form an umbrella of grout over an underground installation.

"""Strikeoff"" or ""Screeding"" the Concrete" Staightedges are used to strikeoff or screed the concrete. This process removes excess concrete and brings the top surface of the concrete to proper grade. This step in the finishing operation is the most important in producing a true plane surface and takes place immediately after the spreading of the concrete.his process removes excess concrete and brings the top surface of the concrete to proper grade.
