Any deterioration of concrete by freeze-thaw action alkali-silica reactivity (ASR) or other means accelerates the rate at which ettringite leaves its original location in the paste to go into solution and recrystallize in larger spaces such as voids or cracks This is because both water and space must be present for the crystals to form The space can be provided by cracks that form due to

Self-healing of cracked concrete a bacterial approach Proceedings of the 6th International Conference on Fracture Mechanics of Concrete and Concrete Structures 3 1821–1826 Google Scholar If long-term viability were improved microorganisms could be utilized to create or "grow" living building materials (LBMs) with structural and sustained biological functions

The International Union of Laboratories and Experts in Construction Materials Systems and Structures (RILEM) was founded with the aim to promote scientific cooperation in the area of construction materials and structures worldwide This mission is achieved through collaboration of leading experts in construction practice and science including academics researchers industrialists testing


Self

The natural self-healing ability of concrete known as autogenous healing has been understood for around 20 years The effect can be seen in many old structures which have survived for such long periods of time with only limited maintenance Cracks in old concrete structures such as Roman aqueducts and Gothic churches have been seen to heal when moisture interacts with unhydrated

Engineered Cementitious Composite (ECC) also called Strain Hardening Cement-based Composites (SHCC) or more popularly as bendable concrete is an easily molded mortar-based composite reinforced with specially selected short random fibers usually polymer fibers Unlike regular concrete ECC has a strain capacity in the range of 3–7% compared to 0 01% for ordinary portland cement (OPC

The USSD Committee on Materials for Embankment Dams has prepared this White Paper on Materials for Embankment Dams The paper provides an outline of important points that need to be recognized and understood when selecting material for use in embankment dams It covers soil materials rockfill materials granular filters and drains asphalt concrete as a water barrier concrete facing

A new generation of robots that can 'self-heal' its jelly-like robotic arms is being developed The European Commission-funded € 3 million SHERO (Self HEaling soft RObotics) project led by the Free University of Brussels (VUB) and the University of Cambridge will strive to create robots that will detect the damage to their polymer skins and 'heal' themselves without the need for any

Self-concept tends to be more malleable when people are younger and still going through the process of self-discovery and identity formation As people age self-perceptions become much more detailed and organized as people form a better idea of who they are and what is important to them

Reactive Powder Concrete (RPC) is an emerging technology that lends a new dimension to the term 'high performance concrete' It has immense potential in construction due to its superior mechanical and durability properties compared to conventional high performance concrete and could even replace steel in some applications The development of RPC is based on the application of some basic

High Strength Concrete Self–compacting Concrete are gaining widespread acceptance Apart from the basic structural materials modern projects require a variety of secondary materials for a variety of purposes such as construction chemicals waterproofing materials durability aids etc The paper highlights some of the recent developments

Self Consolidating Concrete

Self-consolidating concrete (SCC) is recognized as one of the greatest advances in the concrete industry Using new admixtures and some mix modifications we can now produce concrete that flows easily without segregating (where the coarse aggregate separates from the cement paste) Concrete that segregates loses strength and results in honeycombed areas next to the formwork It is the self

Auto-claved Aerated concrete blocks are new to civil industry It is replacing the current usage of red bricks As it has a many features when compared with the traditional red bricks You can learn some of them from below [NO_TOC] Benefits of AAC Blocks The nominal size of AAC block is 9″ X 8″ X 4″-12″ When compared with the volume of normal redbrick with the AAC bricks Volume of 1
