Info

If galvanized sheets are used, ensure that they are properly secured tothe laths so as to ensure adequate resistance in high winds.Allow appropriate overlaps to ensure that the edges of the sheets canbe bent over to prevent lift in high winds.Roofing nails should be galvanized and have large steel washers attheir headsUSE NAILS LIKE THIS...OR USEGALVANIZED STEELWASHERS LIKE THIS.Nail with wide heads and large steel washersNails do not hold as well as screwsUse proper drive screws for corrugatedgalvanized roof sheets.Be sure that the screw go into the purlingsat least two (2) inches.Use large washers under the screw headsto prevent the roof sheets from tearingwhen pulled upward by high winds.Drive ScrewRemember to use sufficient screws so thatthe heads will not tear through.5.2.2 Concrete Blocks - The use ofsolid or hollow concrete blocksinstead of the traditional bricksand stone buildingconstruction is desirable formeeting the demand of goodquality; speed ofconstruction andoverall economy.51
5.2.3 Cement - The commonly used cements in building constructionare as follows:33 grade Ordinary Portland cement (OPC)43 grade Ordinary Portland cement (OPC)53 grade Ordinary Portland cement (OPC)Portland Pozzolana cement (PPC)Blended cement33 grade means that the strength of OPC is 33 Mpa (1 N/mm**2 = 1Mpa = 10 kg/cm**2) at 28 days age.For general construction, 33-grade cement is the best. 53-grade highstrength cement should not be used as far as possible.THE CEMENT MORTAR OR CONCRETE MUST BE USED WITHIN 30MINUTES OF ITS PREPARATION. THE UNUSED MORTAR ORCONCRETE MUST BE REJECTED.The pozzolana cements contain up to 35% finely blended fly ash andare quite satisfactory for use in general construction. They are slowto gain strength in the first two or three weeks, however, after 28days, their strength is at par with 33 grades OPC. The pozzolanacements are more durable than OPC.Unit of MeasurementMpa - Mega Pascal (Pressure)N/mm**2 - Newton per Millimeter Squared (Stress)Kg - Kilogram (Weight)Cm –Centimeter (Length)MONTH OF MANUFACTURE - A bag of cement contains 50 kg of cement.The cement bag carries the WEEK / MONTH and YEAR of manufacture.The cement should be used at the earliest but not later than 3 monthsfrom the date of its manufacture. In any case, the cement should be freefrom lumps and balls at the time of use.STORAGE OF CEMENT - The cement should be stored in a covered roomhaving proper ventilation and free from humidity. It should be stored atleast 15 cm above the floor. The cement should be stacked such thatthere is free circulation of air all around each stack.52
