While some fields of civil engineering endeavour, and some materials, are heavily researched and published, the performance of construction materials and systems attracts far less interest and coverage
Construction Materials from the Institution of Civil Engineers is a recent addition to the suite of ICE Proceedings, and has been established with the aim of encouraging research and practical discussion in the field of performance of construction materials and systems.

Construction Materials addresses, among other subjects
The journal is edited by a distinguished editorial advisory panel and has a broad scope to embrace engineers working in both design and construction.

Construction Materials covers areas such as the procurement, specification, application, development, performance and evaluation of all materials used in construction and civil engineering. Coverage is also provided of the aspects which need to be taken into account when selecting materials: including embodied energy, environmental impact, service life, refurbishment, recycling and reuse.

In this study, the effects of tuff natural pozzolan on properties of Portland cement were investigated. The durability and mechanical properties of concrete made by these cements were studied. It was found that using the natural pozzolan does not significantly affect the mechanical properties of the Portland cement. Furthermore, the natural pozzolan-containing concrete did not perform well in freeze and thaw and sulfate expansion tests. Considerable improvements in depth of water penetration, expansion due to alkali—silica reaction, alkali reactivity and a slight improvement in chloride ion permeability were observed.
