Steel Specification165 viewsSteel is sold as light, medium, full or industrial (?¹‚?¸£?¸§?¹??¸«?¸??¹?) which is a confusing system. The actual specification which refers to the strength required to deform 1 mm strand is printed on the side of the rebar, in this case SD30, on this 12 mm rebar. Only the full grade was used on all 6, 9 and 12mm throughout the project.dozer

External Render143 viewsThe aerated blocks again use a specific product for the external render. It is a ready mix cement skim coat type product. It is easy to work and makes for a smooth and nice render finish. The final thickness of the walls will be 12.5 centimeters so this is being applied about 2.5 centimeters on each side. dozer

Cinderblocks Form Work126 viewsThe cinder blocks are used as form work for the entire ground beam. The cinder blocks will remain after the pour and become part of the flooring material and the exterior walkway. dozer

Floor Structure with Damp Course113 viewsThe floor rebar is spaced at 20 centimeter intervals and red bricks are used as spacers. The damp course material is a heavy thick black plastic which is hard to find. It is more durable and resistant to tearing. The normal clear plastic is problematic and should be avoided. Of course, any damp course is better than no damp course!dozer

Compactor109 viewsThe ground within the ground beam is new dirt which has been brought in, due to the fact that the floor level of the house will be higher than the original ground level. It is first watered and allowed to settle naturally. Then a compactor is used for further compression prior to the pouring of the floor.dozer

Floor + Ground Beam Pour106 viewsThe concrete being poured also has a water proofer as a double protective factor to ensure the damp course. The ground beams and floor is being poured. The floor pour is 10 - 12 centimeters. dozer

Ring Beam Form Work105 viewsThe form work for the horizontal ring beam is made of plywood. Notice 9mm rebar strips are used to ensure that the form work doesn't deform during the pour. dozer

Frame on Spacers100 viewsThe footing frame sits on spacers to ensure it sits equidistant within the footing. dozer

Floor Level100 viewsThe ultimate target floor level is indicated by the prepoured concrete cone in the middle of the picture. Once the CPAC is poured this provides a reference for the leveling process. Note that the finished poured floor is not exactly level, the ultimate leveling occurs during the laying of the ceramic floor tiles. dozer

Red Brick Spacers99 viewsRed brick can also be used as spacers (alternatively from the concrete spacers with wire ties) as needed. These are used to center the ground beam framework equidistant within the cinder block form work. dozer

Concrete Samples for Compressive Test98 viewsThe floor and foundation are poured using CPAC 280 steng (which equates to 280 ksc or 280 kilograms per square centimeter of compressive stregth). The slump is 12 - 14 centimeters which is on the dry side for extra strength. The samples will be further analyzed at the factory and a report certification sent. dozer

Ring Beam98 viewsA ring beam is run horizontally around the entire structure below the window openings. Here we see the beam frame work in place. dozer
