Composition of cement. Introduction Portland cement gets its strength from chemical reactions between the cement and water. The process is known as hydration.This is a complex process that is best understood by first understanding the chemical composition of cement.
Differences in mechanical properties of Q345B and Q355B Q345B and Q355B steel plates are delivered in such conditions as control, normalizing, normalizing + tempering, thermomechanical rolling (TMCP), etc. If necessary, Z-direction function experiments are required, such as Q345D-Z15, Q345D- Z25, Q345D-Z35, etc. The flaw detection level has the first, second and third national standard detection.
GB/T1591 Q345D hot rolled high strength low alloy structural steel plates. In grade Q345D, Q is the symbol for yield strength, 345 means Q345D steel can bear a minimum yield strength of 345MPa. Moreover, GB/T1591 Q345D steel is a kind of Carbon and Low-alloy High-strength Steel, and GB/T1591 Q345D Steel Plates find their broad application areas in Construction of Bridges, Highway

Q345R Pressure Vessel Steel Plate for Boiler ManufactureQ345R Steel Introduction:. Q345R is a combination of 16Mng, 19 Mng and GB6654-1996, and GB150 specified the thickness range is 3 ~ 200mm. The limit value of the tensile strength with low carbon content and standard is no more than 540Mpa, and it has good weldability, in common conditions cold and hot crack are not easy to form.
Q345b steel plate for buildings grade - The Alpha GamesQ345 steel specification:Q345 steel belongs to 16Mn steel grade, usually it is produced in hot rolled state, hot rolled steel plate, hot rolled steel coil/sheet, it has comprehensive mechanical and welding property, as it shows good performance in structural purposes, it is widely used as welding structural part in manufacturing of ship, railway and vehicles, bridges, boiler, pressure vessel
Q355 steel is a Chinese low alloy high strength structural steel, which replaced Q345, the material density is 7.85 g/cm3. According to GB/T 1591 -2018, Q355 has 3 quality levels:Q355B, Q355C and Q355D. Q is the first letter of Chinese Pinyin:qu fu dian, which means Yield Strength, 355 is the minimum value of yield strength 355 MPa for steel thickness 16mm, and tensile strength is 470-630 Mpa.
