Waste Recycling Concrete Floor Slabs

 

Waste Management Facilities require a more durable concrete floor than comparable buildings due to the nature of their operations. Here at Nationwide Concrete Flooring we understand this, and are able to work alongside clients and contractors in order to offer a highly efficient, effective and durable concrete floor that with good planning, design and investment should stand the test of time and require less maintenance.

“It has been observed that some of these concrete floors have experienced extremely high levels of abrasion resulting in rapid surface loss. Wear rates in excess of 25mm in one year have been reported”UK Concrete Society Concrete Advice Sheet No. 49 May 2013
 

In most circumstances the concrete floor for such a facility will require replacement at some time during its operational life. However, a steel fibre reinforced concrete (SFRC) jointless slab design is expected to have a longer life expectancy and is a better investment of capital for waste management facility new builds, than your typical reinforced concrete floor with contraction inducing saw cuts. The lack of joints within a SFRC floor reduces the number of weak points within the floor which are likely to be susceptible to damage and abrasion.

Nationwide Concrete Flooring also highly recommend the use of a ‘dry shake’ floor topping to increase the strength and durability of the floor in such facilities. This can be discussed with the sales team to examine various options including colour and cost. However dry shake topping should not be used to supplement a cheaper less durable floor which bring with it inherent weaknesses.

Good planning and investment at the design stage of projects can have positive impacts upon whole life cycle costing models for the end user. Nationwide Concrete Flooring will work with you to achieve the right balance between investment and life expectants to best suit your needs and requirements.

 

nwdg-grabber-ed

Concrete floor slabs at waste recycling facilities have to out up with extremely aggressive usage for heavy trafficking and impact damage. The photo above shows a large grab that picks up the waste from the concrete floor and places the ware into a large concrete chamber. These new waste to energy plants are of an enormous
scale and service large areas of the country. We at Nationwide Concrete
Flooring have all the necessary experience to both design and construct
concrete floor slabs at waste recycling facilities.

At Nationwide Concrete Flooring we readily promote the use of “by products” within our concrete mixes in order to reduce the carbon footprint on our projects. One of these products is blended cements in lieu of concrete containing 100% ordinary Portland cement, now commonly referred to as CEM 1. Below is some brief text on GGBS (ground granulated blast furnace slab) and how they can benefit both the end product itself and also the environment.

The Future For GGBS

During the past 30 years there has been a sizeable growth in the use of cementitious additions and blended cements, progressively replacing the primary use of Portland cement within concrete mix design and proprietary product profiling. The reasons for this are numerous and unsurprisingly include concrete durability. Concrete durability is an essential requirement and is well captured within the codes that thoroughly advocate the use of cementitious additions and blended cements to counteract various known forms of concrete deterioration. As an example , BRE Special Digest 1 this edition identifies that “the main compositional factors that determine the resistance of concrete to aggressive ground are its water cement ratio and type of cement or combination used.” The document extols “the excellent performance of concrete incorporating ground-granulated blast-furnace slag cements”

 

 

 

By-product

 

The importance of using readily available by-product materials and reducing overall energy consumption is becoming ever more apparent. Typically, an ore feed comprising about two-thirds iron will yield up to 0.3 tonnes of blast-furnace slag per tonne of crude iron. The contraction of the UK steel industry will clearly have an impact on how the raw materials for GGBS are sourced, but it is unlikely to affect either supply or demand for the end product. Both granulated blast-furnace slag and GGBS are already imported into the UK. The closure of our domestic steel plants ( plus the fact that other substitutes such as fly ash will progressively become scarcer ) should result in those imports increasing in the coming years as the construction industry strives to reduce the embodied carbon content of concrete.

Nationwide Concrete Flooring is officially certificated for the carrying of waste.

This is further reassurance for our clients that the company is correctly register with the Environment Agency.
