Bond :


The important assumption made in the theory of reinforced concrete is that there is a perfect bond between steel and concrete.they have to act together with out any slip. due to bond only the force will be transeferred to the steel from the surrounding concrete and to concrete from steel.

Bond stress:

Bond stress is the shear stress acting parallel to the bar on the interface between the reinforcing bar and the surrounding concrete.hence,it is the stress developed between the contact surface of steel and concrete to keep them together.its resists any force that tries to pull out the rods from the concrete.

Bond is developed due to combined effect of

a) adhesion between concrete and steel
b) friction (provided by gripping of bars due to shrinkage of concrete)
c) interlocking of ribs in bars with concrete

Bond stress depends on grade of concrete,diameter of the bar,bar profile condition,nature of force in the bar,grouping of bars,bends and hooks in the bar. the values of design bond stress precribed by IS 456-2000 are given

foaming agent for clc blocks and project report,how to make protein based foaming agent ,foaming agent for clc light weight concrete bricks,foaming agent ratios,foaming agent for roof insulation and wall panels,foaming agent raw materials,clc bricks manufacturing process contact:09966871942,8712383363 foaming agnet is our unique enzyme based foaming agent. This Foaming Agent is manufactured in a unique fermentation process and not through the main used method of acid hydrolyzes. Our Making process enables us to separate exactly the needed proteins for specific characteristics (stability, foaming characteristics, etc.) according to their molecular weight. This method leads to excellent products with advanced characteristics and competitive prices. It causes no chemical reaction with the surrounding matrix but serves solely as wrapping material for the air to be encapsulated in the concrete (mortar) Features: protein based foaming agent it is used for cellular light weight bricks/blocks or foam concrete bricks/blocks oam density 80-90gms/lts foam density 80-90gms/lts ratio around 1:45 ratio Foam generated with our protein based foaming agent with mixing of air and water is stable. it is added into cement slurry and blended with blender to form a homogeneous dispersion. is safe for use and has no harmful effect on human being. It can be successful treated in biological waste water treatment systems after proper dilution. Stability: Stability of bubbles is 1.0 to 3.0 hours, depending upon the temperatures and environmental conditions Stable, long-lasting foam blanket provides excellent burnback resistance. Suitable for use with fresh or sea water. Compatible with standard proportioning and air aspirating foam making equipment. Suitable for use with foam compatible dry powder extinguishing agents. it is used for cellular light weight bricks,wall panels and roof insulation. some of our clients: we supply foaming agent and foam generator to all the cities in gujarat Mahuva,Jamnagar,Baroda,Mangrol,Bulsar,Jakhau,Tuna,Vapi,Div, Okha,Rajula,Ghogha,Bhagwa,Morbi,Bharoch,Godhra,Porbandar, Sika,Keshod ,Ahmedabad,Surat,Bhuj,Bedi,Mundra,Kundla,Jodia,Bilimora, Ankleshwar,Dwarka,Kotda, Talaja,Broach,Dadra,Halol,Veraval,Vadodara,Chhani/Vadodora, Rajkot,Sachin (Surat), Jafarabad,Bhavnagar,Cambay,Mandvi,Khambhat,Gandhidham,Kandla, Umbergoan, Kapadra(Surat)Beyt,Kodinar we supply foaming agent,clc mixer and foam generator to all the cities in maharastra
