Abstract The world today has started facing bigger problems related to the concrete industry, especially with becoming most extensively used construction material in world. At a time like this, where more eco-friendly substitutions are stringent, it calls for comprehensive approach producing recycled from aggregates (RCA). This study is an extension previous studies involving composite utilizat...

Reducing the consumption of cement with simultaneous utilizing waste materials as cement replacement is preferred for reasons of environmental protection. Blended cements consist of different supplementary cementitious materials (SCMs), such as fly ash, silica fume, Ground Granulated Blast Furnace Slag (GGBFS), natural pozzolans, etc. These materials should be chemically activated to show effec...

This work describes the newly discovered zeolites in eastern region of Cuba. In researched area, there have been no previous studies natural zeolite exploration. Therefore, results shown here are new. The main object this research is to analyse five samples and demonstrate their pozzolanic capacity possibility usage industrial manufacturing cements. study was performed by X-ray diffraction (XRD...

Roller Compacted Concrete (RCC), is a concrete with zero slump, which is used in damming and road pavement. Roller Compacted Concrete Pavement (RCCP) bear heavy traffic loads and severe weather conditions. This type of concrete is due to its economic and environmental capabilities, including reduced construction and maintenance costs, longer durability and longer lifetime, as well as environmen...
