Key technical parameters for preparing HSLC with the strength range of LC40～LC60 were confirmed. Lightweight aggregate concretes of LC40～LC60 with high workability were prepared with raw materials of high strength lightweight aggregate of class 800 and 42.5# Portland cement.
(2)The resistance to cracking of concretes with the area of 430m~2/kg ground slag at early age are increased,but when the area of ground slag is above 520m~2/kg,the resistance to cracking of concrete at early age is weaker.
Based on experiments of C60 concrete with machine-made sand,this paper studied on the workability,strength,drying shrinkage and durability of the concretes with different weight fractions(3.5%、7%、10.5%、14%) of stone powder and different FA contents(0、11%、17%).
Especially, in a case with no failure and a case with only one failure, the concrete computational methods are presented.
The concrete construction is then utilized for analysis of two portfolio optimization problems for financial market models driven by stable-like processes.
Fairly simple general correlations are derived between the intensity components that are independent of the concrete characteristics of the object.
The corrosion rate varies with the conditions changing inside the concrete structure due to its irregular wetting in an aqueous solution of NaCl.
The correlations are established between the direct UPV and indirect UPV in the concrete casting direction as well as in the horizontal direction and semi-direct UPV measurements via statistical analysis.
These values were suggested as references of engineering applications and of the amendment of the current Chinese design code of steel reinforced concrete composite structures.
Consumption of carbon fiber plates in the reinforced concrete beams strengthened with CFPs
Four-point bending flexural tests were conducted to one full-size reinforced concrete (RC) beam and three full-size RC beams strengthened with carbon fiber plates (CFPs).
Experimental study on fire protection methods of reinforced concrete beams strengthened with carbon fiber reinforced polymer
In this paper, two reinforced concrete (RC) beams strengthened with carbon fiber reinforced polymer (CFRP) and attached with thick-painted fire resistant coating were tested for fire resistance following the standard fire testing procedures.
