Sustainable Concrete Hanson UK

Using Regen can significantly reduce the embodied carbon content of concrete, making EcoPlus a more environmentally friendly concrete option. The level of Regen in EcoPlus concrete can be as high as 70%, which is usually more than twice as much as other cement replacements such as PFA, which would typically be around 30%.

Formwork and Shuttering Pavingexpert

The part of the shutter in contact with the concrete is known as the form lining, while the support timbers are collectively known as 'bracing' and consists of horizontal walers and vertical noggins. The size of timbers used for the bracing depend upon the size of the formwork; a simple 300mm high shutter for a ground slab may use 50x50mm timber to form the walers and noggins, whereas a 1 metre high

Red is the saving on vertical pipework for the saving in height. Electrical Red indicates a saving on the electrical load as a result of savings in cooling load. There is very little in it cost-wise, although the concrete frame compares better in terms of cost/net area, because 7 m2 is saved on the area of stairs, which are shorter.

How to Evaluate Cracks in Poured Concrete Slabs

Other types of concrete cracking such as due to impact or loading are discussed in other articles at this website. Cracks come to the job along with the concrete, riding in the same truck! At a Journal of Light Construction conference (Boston 1985) a lecturer informed us that "Every concrete truck that comes to your job to pour a slab has at least four cracks in it.

Choosing the Right Tool for Concrete Drilling and ...

06/02/2017  Conversely, a rotary hammer is a tool that employs an electro-pneumatic hammer piston to generate high impact energy, which allows it to drill or demolish concrete in all-day applications. Rotary hammers also feature a hammer-only mode for chiseling applications. Many of these tools can be found with SDS-plus and SDS-max bit holding systems. SDS-plus is the right choice for smaller diameter ...

Curing Concrete - How Long it Takes How To Cure - The ...

08/05/2020  Curing is easy to skip in the instant but that will have a major impact on the quality of your finished work. While curing is important for all concrete, the problems that arise from not curing are most obvious with horizontal surfaces. An uncured slab, whether decorative or plain gray, is likely to develop a pattern of fine cracks (called crazing) and once it's in use the surface will have ...

Rules for Fastening to Concrete - Concrete Fastening ...

Explanation: Mechanical type concrete anchors exert outward pressure against the wall of the hole in concrete. This pressure goes out and up the length of the anchor forming what is commonly called a cone of concrete, as it is cone-shaped in appearance. Since anchors derive their holding values from the base material, this cone-shaped area is a picture of the holding values the anchor has ...
