cements and it''s chemical content

    Asphalt Composition- cements and it''s chemical content ,Conventional chemical analysis shows that bitumens contain mainly carbon and hydrogen with small amounts of oxygen, nitrogen and sulphur and trace amounts of metals A typical analysis is 83% carbon, 10% hydrogen, 7% oxygen, nitrogen and sulphur and trace amounts of vanadium, nickel, aluminium and siliconWhat is the difference between opc and ppc cement,To know the difference between OPC and PPC cement follow this link Himanshu Gautam''s answer to What is the difference between opc and ppc cement? Now a days, only PPC cement is available in market, if someone wants to use OPC cement the he/she has to specially order the required quantity.
