Dubai has shared its experience in using green cement in the sustainable concrete industry with the world.
The conference was attended by more than 300 specialists in different concrete techniques from multiple countries such as the US, European countries, China, Japan, and some Arab countries, according to Khalid Mohammed Saleh Al Mulla, Director of Buildings Department at Dubai Municipality, said
Aida Al Harmoodi, head of Consultants and Contractors Qualification Section at Buildings Department, said that the municipality presented its experience in using eco-friendly cement materials in the sustainable concrete industry, and explained its leading role in transforming Dubai into a green city as well as its continuous and sustainable efforts in the improvement, development and innovation fields.
The civic body stressed, during the conference, that the experience has succeeded thanks to the leaders’ directives and support for the leading projects that go in line with the strategic goals of the emirate and the UAE.
Aida revealed Lionel Lemay, President, the US National Ready Mixed Concrete Association (NRMCA), founded in 1930, praised Dubai’s experience and lauded before the audience the right decision taken by the Municipality to mandatory apply green cement to all Dubai building projects, which has multiple benefits.
Lemay hoped it will be applied in the US.
Ahmad Saeed Al Badwawi, head of Research and Building Material Studies at Buildings Department, said that the worksheet submitted by the Municipality addressed the environmental disadvantages associated with the use of ordinary cement, which is considered as non-eco-friendly since its industry and applications result in the emission of carbon dioxide and other toxic substances in huge quantities, harming thus the environment, the public health and safety.
