Replacing cement with waste ash streams in soil stabilisation – less carbon more strength?

Experimental study on the use of RoadCem blended with by-product cementitious materials for stabilisation of clay soils. Authors: Samuel J.Abbey  Eyo U.Eyo  Chukwueloka  A.U.Okeke  Samson Ngambi Highlights Shear strength increases due to the formation of C‑S‑H gel and particle bonding. Cement-GGBS mixtures change stabilisation mechanism from glue to wrapping effect. Mixture of cement, GGBS and […]

What the is best way to construct a temporary access road?

What the is best way to construct a temporary access road? Temporary access roads are required across and to construction sites. They provide access for heavy construction vehicles carrying materials and equipment needed at the site and occasional movement of tracked construction vehicles. Because these roads are required for only temporary use, they are often […]

Stabilisation of peat with RoadCem

Stabilisation of peat with RoadCem Construction of Tesco Store close to Breydon Water, Great Yarmouth. RoadCem was used to stabilise the salt water sedge and peat on the site. Area’s containing Peat or Peat bogs are difficult to implement in a durable construction system. RoadCem now makes the big difference and extends the field of […]

Carbon Neutral Concrete Blocks without OPC

Carbon Neutral Concrete Blocks without OPC Cement production generates large quantities of fine grained a (<250µm grain size) waste material called cement kiln dust (CKD). Abeln et al. (1993) define CKD as a “fine particulate matter that consists of entrained particles of clinker, raw materials, and partially calcined raw materials”. The production of CKD means […]

Weather and Soil Stabilisation

Weather and Soil Stabilisation With traditional lime/cement soil stabilisation any rainfall during installation can result in a change in the moisture content of the soils being treated. This will adversely affect the structure of the stabilisation and its subsequent performance.  However when RoadCem is added this weakness and/or  failure will only occur in the most […]

Intelligent Hard Shoulders

Intelligent Hard Shoulders Roadside Management and Erosion Control for longer lasting Roads Integrated roadside management programs will always be needed because they combine the multiple missions of roadside vegetation control, roadside beautification, motorist safety, erosion control and preventative maintenance in one cost effective package. Every year accidents take place with cars slipping off the road. […]
