What is Mass Concrete?

Neenu S K — Fri, 04 Feb 2022 18:23:24 +0000

Mass concrete is defined as heavy volume concrete work with large dimensions and boundary conditions that are prone to elevated temperatures due to a higher rate of the heat of hydration. The high temperature in concrete results in high thermal stresses, cracking, and reduced long-term strength gain. Hence, the main factor distinguishing mass concrete from […]

NeoConcrete: Applications and Advantages

Madeh Izat Hamakareem — Mon, 27 Dec 2021 18:33:56 +0000

NeoConcrete is a construction material that creates a continuous coating of 0.4 cm thickness for walls, floors, and exteriors that resembles terrazzo or granite finish. It is produced from a mix of cement, decorative aggregate, and resin. The most common use of NeoConcrete is as a highly resistant flooring and polished finish. This makes it […]

What is Alkali-Activated Concrete (AAC)?

Neenu S K — Sun, 16 May 2021 04:53:02 +0000

Alkali-activated concrete (AAC) is defined as a class of cement-free concrete that is an alternative to Portland cement concrete (PCC). In AAC, the cement is entirely replaced by an alternative binder. Instead of using ordinary portland cement (OPC) and water, AAC uses other supplementary materials like blast furnace slag (BFS) or fly ash (FA) along […]

How can Embodied Carbon be Used to Reduce Global Warming?

Madeh Izat Hamakareem — Sat, 01 May 2021 22:48:55 +0000

The use of carbon dioxide directly i.e. without chemical modification, or after chemical conversion processes for the production of building construction materials is a key strategy to mitigate climate change and use resources efficiently. Researchers have been relentlessly conducting investigations to implement this strategy in the production of building materials, and the results have been […]

Building with Textile-Reinforced Concrete: Important Properties and Advantages

Neenu S K — Fri, 13 Nov 2020 16:48:16 +0000

Textile-reinforced concrete (TRC) or fabric-reinforced cementitious matrix (FRCM) is a composite concrete material that employs textile reinforcement instead of steel reinforcement. TRC is being widely used in construction for the past two decades and is a promising solution for retrofitting and strengthening concrete structures. The fabrics or textiles used for TRC are jute, glass, fiber, […]

Properties of Materials for Underwater Concreting

Raghvendra_Rai — Sat, 23 May 2020 17:40:09 +0000

Concrete mix design for underwater concreting requires the selection of suitable materials and proportioning to produce concrete to meet the requirements of a specified application. Which mainly concentrates on the properties of workability/flow, compressive strength, and durability. Characteristic/Target Strength Relationships Detailed physical observation is difficult for concrete placed underwater. Thus, while UWC specimens cast in […]

Silica Fume Concrete [PDF]: Properties, Advantages, and Applications

Madeh Izat Hamakareem — Wed, 22 Apr 2020 19:55:00 +0000

Silica fume concrete is composed of cement, silica fume, fine aggregate, coarse aggregate, and water. Fresh and hardened properties of silica fume concrete is superior to conventional concrete. For instance, it has higher compressive and flexural strength. The durability of this type of concrete is superior to conventional concrete. Resistance against freezing and thawing and […]
