High-performance concrete has been primarily used in tunnels, bridges, and tall buildings for its strength, dura- bility, and high modulus of elasticity (Fig.  strength • High early strength 299 HOME PAGE meeting durability factors for air-void sys- tem and resistance to chloride 

011061, Bucharest, Romania This paper refers to the preparation of durable performance concrete using superplasticizer additives. The study revealed  to obtain concrete strength above 100 MPa, improves the surface appearance, can be placed in difficult areas, and it does not vibrate.

Methods and compositions of the invention involve the use of crude intermediate fermentation broth, derived from industrial glucose fermentation processes  Polycarboxylic acid type superplasticizers are conventionally known in the concrete arts.

The cement additive according to any of Claims 1 to 3, wherein R 3 in said general formula (1) is a dicarboxylic acid residue.  However, it is a drawback with the combined use of a polycarboxylic acid cement dispersant and an AE agent that the amount of air entrained progressively

State-of-the-Art Report on High-Strength Concrete

However, in recent years, the applications of high-strength concrete have increased, and high-strength concrete has now been used in many parts of the world.  and columns at an early age. Accelerators used to increase the rate of hardening will normally be counterproductive in long- 

It is also shown that the use of WRA will give a higher initial concrete compressive strength (up to 28 days) by 10% compared to the control mixture. Other  The use of superplasticizers may produce high strength concrete (compressive strength up to 22,000 psi)
