The Challenge

To support the development of Madinat Al Wurood – commonly known as the City of Roses – a new suburb located in the north of the Taif governorate in the Kingdom of Saudi Arabia, the Al-Jazera Concrete Company (JCC) partnered with CDE to commission a new sand wash plant to improve the efficiency of its operation, the compressive strength of its concrete, and to reduce its environmental footprint.

In the first phase of the project, over nine million square metres of land, including 112km of road networks and 5,400 residential villas will be developed. To date, JCC has supplied over 425,000mof poured concrete to the project to support the construction of over 1,500 prefabricated residential units.

To improve efficiency, concrete strength and minimise environmental impact, JCC sought a solution to efficiently process and enhance the sand equivalent (SE) value of the crusher fines used in its concrete mix, which CDE determined to be around 50%.

SE values indicate the proportion of dust and clay-like material in feed material. A lower value indicates a higher proportion of this material. The higher the SE value the stronger the concrete, which then requires less cement to bind, a costly process both commercially and environmentally.


The Solution

To increase the SE value of JCC’s feed material, our team proposed a wash plant set up comprising two of its patented EvoWash™ sand classification and dewatering plants coupled with the AquaCycle™ thickener for water management.

A compact, modular sand washing system, the EvoWash washes and deslimes the crusher fines by ensuring low moisture product with the help of its high frequency dewatering screen. The hydrocyclone technology provides unrivalled control of silt cut points and eliminates the loss of quality fines. 

Prior to commissioning, JCC visited Al-Tawi, another of our customers in Saudi Arabia operating its washing technology as part of its ready mix concrete production.


The Results

Processing up to 300 tonnes per hour (tph) of material, the solution is producing 200tph of 0-5mm sand with a final SE value of 88%, up from around 50% prior to commissioning and significantly exceeding acceptance criteria of 70%.

Using CDE manufactured sand in JCC’s concrete mix design is helping to lower the production of CO2 by optimising the concrete mix with less cement required to obtain the same compressive strength.

JCC’s Taif area manager, Mr Abdelmajeed Al Kurdi, said: “As well as driving down cement consumption and boosting the SE value of our material to produce a higher quality end product, the solution designed and engineered by CDE has also delivered significant efficiency gains in terms of water management on site.

“Already, the integration of our first CDE wash plant into the operation has transformed our business and given us a competitive advantage in the local market. We’re able to exceed expectations and that will position us well for future success as we tender for high value projects of major public interest.”
