“Ground Granulated Blast Slag (GGBS) In Concrete – A Review”
GGBS concrete gains strength more steadily than equivalent concrete made with Portland cement. For the same 28 day strength, a GGBS concrete will have lower strength at early ages but its long term strength will be greater, the reduction in early strength will be most noticeable at high GGBS levels and low temperatures.
Durability - Portland Cement Association
The heavily traveled Wacker Drive replacement in downtown Chicago was designed for a 75- to 100-year life. The design service life of most buildings is often 30 years, although buildings often last 50 to 100 years or longer. Because of their durability, most concrete and masonry buildings are demolishe
Durability Studies on Glass Fiber Reinforced Concrete
Abstract. In the present experimental study, glass fibers were used in varying dosages of 0.5, 1.0, and 1.5% of cement content (by weight) as partial cement replacement to cement in concrete mix. The effect of different dosage of glass fibers on the bond strength between steel and concrete in reinforced concrete was investigated.

Use of Limestone Fines to Reduce Permeability of Concrete for Durability Improvement
Traditionally, the use of limestone fines (LF) in concrete is to replace either part of the cement or part of the fine aggregate, notwithstanding this, the authors are advocating that the LF should be better used as cement paste replacement, which is expected to improve the durability and sustainability of concrete …
Durability Performance of Bridge Concretes, Part II
ABSTRACT: A study was undertaken on the durability of high-strength concrete (HSC) produced using locally available materials in the State of Missouri. Thirty-six (36) different mixtures were produced as HSC. 30 % fly ash replacement by cement weight was
Engineering Center - Improving Concrete Durability with
The biggest sustainable result of using crystalline technology in concrete is increased durability and longevity of concrete structures. That longevity means there is likely less maintenance and repair work, and less need to replace a damaged or deteriorating structure.

Durability of mortar using waste glass powder as cement replacement
Highlights Glass powder is thoroughly analysed as a partial cement replacement material in mortar. Testing is carried out far beyond the usual mechanical testing and ASR by most authors. Chloride ingress, carbonation, sulphate attack and sorptivity are also considered for durability assessment. SEM demonstrated effect of fine glass particles well encapsulated into a dense matrix. This holistic study …
