Structural and non-structural cracks in concrete – know the difference
Structural and non-structural cracks in concrete differ primarily in their causes, implications, and the urgency of their repair. Structural Cracks: Non-Structural Cracks: Summary Table: Feature Structural Cracks Non-Structural Cracks Causes External loads, seismic activity, design flaws Thermal changes, plastic and drying shrinkage, minor settlement Implications Compromise structural integrity, potential collapse Affect appearance, can lead to…

Cracks in Concrete
Cracks in concrete are a common issue influenced by various factors. According to Layang (2022), cracks are unavoidable but can be controlled in size. They are categorized into non-structural and structural types, caused by factors ranging from material properties to external loads. Abou-Zeid et al. (2007) explain that cracks can signify both minor and major…

Type IL cement exhibits improved resistance to chemical attacks compared to traditional Portland cement
Type IL cement exhibits improved resistance to chemical attacks compared to traditional Portland cement (Type I), primarily due to its composition and the incorporation of additional materials that enhance its durability in aggressive environments. The increased limestone content in Type IL cement contributes to a denser microstructure, reducing permeability and enhancing resistance to chemical ingress.…

How does the carbon footprint of Type IL cement compare to traditional Portland cement?
Type IL cement, also known as Portland-Limestone Cement (PLC), has a lower carbon footprint compared to traditional Portland cement (Type I) due to several factors. The primary advantage of Type IL cement is its increased limestone content, which means that less clinker, the most carbon-intensive component of cement, is needed in its production. Studies have…

What is Type IL Portland Cement?
Type IL cement, also known as Portland-Limestone Cement (PLC), offers significant environmental benefits compared to other types of cement. Primarily, Type IL cement integrates a higher percentage of limestone into the cement mix, which results in a lower carbon footprint during its production. This reduction is primarily due to the decreased need for clinker, the…

Type IL Cement is Here to Stay
Type IL cement, also known as Portland-limestone cement (PLC), is increasingly being used in place of Type I/II cement for several reasons. Here are some key advantages of using Type IL cement over Type I/II cement: In summary, Type IL cement offers environmental benefits, improved workability, and comparable performance to Type I/II cement, making it…
