·Green concrete uses waste materials and less energy in production resulting in lower carbon dioxide emissions than traditional concrete It contains fly ash as a cement replacement which reduces CO2 from cement manufacturing Green concrete provides benefits like increased strength and durability while reducing the environmental impact of
·13 Steps Involved in manufacturing process There are mainly four steps involves in manufacturing process of AAC Bricks 1 Raw Material Preparation Fly ash Fly ash is mixed with water to form fly ash slurry Fly Ash is usually a by product of thermal power plants and is an important raw material in the manufacture of AAC Blocks Slurry thus formed is
·10 Advantages of Roller Compacted Concrete RCC Concrete • Reduced cement consumption as the leaner concrete mix can used • Formwork costs are minimized or eliminated because of the placement method • No concerns about high heat release while the concrete is • The cost of transporting placement and compaction of are minimized because
·10 Evolved asahybrid from silicate& Polycarboxylatecement DEFINITION DEFINITION A cement that consists of a basic glass & an acidic polymer which setsA cement that consists of a basic glass & an acidic polymer which sets by an acid base reaction between these an acid base reaction between these components
·Aggregates ppt Download as a PDF or view online for free It defines aggregates as inert materials mixed with cement or lime for mortar or concrete Aggregates are classified as fine or coarse based on particle size Common fine aggregates include sand from various sources while coarse aggregates include crushed stone and gravel
·4 abStract Cracks in concrete are inevitable and are one of the inherent weaknesses of concrete Water and other salts seep through these cracks corrosion initiates and thus reduces the life of concrete So there was a need to develop an inherent biomaterial a self repairing material which can remediate the cracks and fissures in concrete Bacterial concrete
·5 CONCRETE Concrete is a composite material composed of gravels or crushed stones coarse aggregate sand fine aggregate and hydrated cement binder and imparts considerable hardness to the mixture The cement reacts chemically with the water and other ingredients to form a hard matrix which binds all the materials together into a durable
·Apply it on a piece of a glass plate And keep it underwater for 24 hours If hand is poured inside the bag full of Cement it should feel cold inside If the cement feels somewhat warm then it indicates the start of hydration of cement due to absorption of moisture After 24 hours cement paste should set and not crack
·32 Bagasse ash as replacement for cement in concrete 32 REFERENCE Miss Vaishali D Girge Effect Of Use Of Bagasse Ash On Strength Of Concrete International journal of innovative research in science engineering and technology 2 2013 2997 3000 H R Eramma Yashwanth M K Keerthi
·2 Cement • In the most general sense of the word a cement is a binder a substance that sets and hardens independently and can bind other materials together Cement used in construction is characterized as hydraulic or non hydraulic • Hydraulic cements Portland cement harden because of hydration chemical reactions that occur independently of
·Seminar Topics for Civil Engineering with ppt and PDF report 2024 We civil engineers have lots of stuff to do throughout the are so many seminars project reports vivas and exams in our complete engineering degree
·SPECIAL CONCRETES Presenting a seminar on Ferro Cement Parikshit N H 2 INTRODUCTION Ferro cement is a type of thin wall reinforced concrete It is commonly constructed of hydraulic cement mortar reinforced with closely spaced layers of continuous and relatively small size wire mesh The mesh may be made of metallic or other suitable
·6 Glass ionomer is the generic name of a group of materials that use silicate glass powder and aqueous solution of polyacrylic acid Kenneth J Anusavice • Glass ionomer term coined by wilson & kent glass alumino silicate glass particles ionomer poly carboxylic acid The glass ionomer family of restorative materials has evolved during the past 30 years into a
·3 Most of these problems have more or less been solved in newer generations of glass ionomer cement Setting has been accelerated and hydration problems have been reduced However unlike composites their use in stressed situations is still questionable The most common indication of the newer heavily filled reduced particle size glass ionomer
·Pressure washing of a clogged pervious concrete pavement has restored 80% to 90% of the permeability in some cases • Pervious concrete in freeze thaw environments must not become fully saturated Saturation of installed pervious concrete pavement can be prevented by placing the concrete on a thick layer of 200 to 600 mm of open graded stone
·4 History In 2001 the idea of Light emitting concrete was put forward by Hungarian architect Aron Losonzi Successfully produced the first Light emitting concrete block in 2003 named LiTraCon In 2004 he started a German company named LiTraCon and started producing Litracon commercially Alignment of fibres in a light emitting concrete cube

·concrete is widely used around the world the consumption rate of cement of a country gives the development rate of the country hence concrete is used in most of the construction works concrete tends to crack when there is air voids etc this ill further corrode the reinforcement and cause in destruction of the structure bio concrete is a type of concrete hat
·3 Mortar provides the mass and wire mesh imparts tensile strength and ductility When building Ferro cement structures the sand/cement mortar is applied to the reinforcing wire with a trowel never poured like common concrete work Often a form is used to provide the desired shape Ferrocement is a super reinforced concrete It differs from conventional
·Fiber Reinforced Concrete FRC Seminar and PPT with pdf report Fiber Reinforced Concrete FRC is concrete consisting fibrous material which increases its structural purity It holds short discrete fibers that are uniformly distributed and circumstances oriented This page contains Fiber Reinforced Concrete FRC Seminar and PPT with pdf report
·3 DEVELOPMENT OF SCC In 1983 the problem of the durability of the concrete structures was a major topic of interest in Japan The creation of durable concrete structures requires adequate compaction by skilled workers Solution for the achievement of durable concrete structures independent of the quality construction work is the use of SCC
·Pervious concrete is a type of concrete with high porosity that allows water to pass through reducing runoff It was first used in Europe in the 1800s and became popular again in the 1920s for homes in Scotland and England The mix design includes aggregates cementitious materials and water with void contents between 15 30% and water cement
