Al Kifah KRB to launch green concrete

01 March 2022

Al Kifah Ready-Mix & Blocks (KRB), a leading provider of ready-mixed concrete and concrete masonry blocks products in the Kingdom of Saudi Arabia, is set to launch its green product line under its new slogan “Keep it ConGreen” at The Big 5 Saudi this month.

According to Al Kifah research and development centre, ConGreen concrete boasts a number of sustainable and environmental benefits, whilst providing high durability, improved performance, and better workability and pumpability properties. It also has high passing and finishability, making it suitable for self-compacting concrete.

ConGreen complies with the most onerous durability requirements and provides very low Rapid Chloride Permeability (RCP), water absorption and water permeability properties. With low heat of hydration, temperature rise in mass pours can be controlled thus minimising the risk of cracking.

Al Kifah also offers mixes utilising recycled metal slag aggregates.

ConGreen has a low carbon footprint with a carbon dioxide (CO2) emission factor as much as 30 per cent lower than standard concrete along with higher compressive and flexural strengths compared to concrete with the same cement content.

“We are committed to driving energy efficiency and addressing the global emission challenges. We aim to help build a better community and environment-friendly facilities by producing high-quality concrete such as ConGreen that has a reduced environmental impact and is characterised by its high performance, durability and sustainability, with a low carbon footprint as compared with standard concrete,” says Nigel Harries, General Manager of Al Kifah Ready-Mix.

“‘ConGreen’ is a combination of words ‘concrete’ and ‘green’ and sums up our focus on sustainability by enhancing our green product line and raising the bar in the industry. By using raw materials that have lower carbon emissions such as natural pozzolan and applying the most advanced carbon emission technologies such as embedding recycled carbon dioxide licensed from CarbonCure Technologies Inc from Canada, substantial CO2 savings can be made,” he adds.

In addition, Al Kifah KRB has a range of mixes utilising recycled metal slag aggregates suitable for specialist construction where high density and protection from radiation is required.

In line with Saudi Vision 2030, Al Kifah KRB is enhancing its local and regional resourcing and maximises the use of raw materials produced in-house by group companies such as admixtures (Technical Factory for Concrete Additives – TFCA), aggregates (Alkifah Crushers) and local natural pozzolan.

The company also focuses on controlling waste through the use of reclaimers.

ConGreen concrete boasts a number of sustainable and environmental benefits, whilst providing high durability, improved performance, and better workability and pumpability properties.

Al Kifah KRB says its green concrete has been approved by Saudi Aramco and has been used in numerous projects such as King Salman International Complex for Maritime Industries and Services project, East West pipeline and Waset projects.

It has also been used for the Al Moosa Hospital, a private project in Al Ahsa, where it has provided EPD certification and complies with the LEED Gold standards.

Established in 1980, Al Kifah KRB has grown from just one factory to more than 27 branches all over the kingdom. Since then, the company has expanded to nine main cities with a team of more than 1,500 employees and a fleet of over 1,000 vehicles with a total production capacity of more than 3,500 cu m per hour of ready-mixed concrete and more than 120,000 concrete masonry blocks per day.
