MyWeku Restaurant: Time to catch our breadth as we wait for the curing of the concrete
Since the 8 pillars were put in place the connecting beams have also been put in place, albeit with a number of bamboo sticks holding them up.
I received this message from Dad which describes the stage we are in a lot better than I could.
On Wednesday iron rods were fabricated for the 8 pillars. Yesterday these were set in concrete, wooden boards formatted around 4 and concrete poured for 4 pillars. This morning the boards were removed. The remaining 4 will be tackled today and boards removed tomorrow. In 2 weeks time the beams on the pillars will be in place and after the concrete works have matured, we will tackle the roofing. This will involve purchasing the wooden roofing materials required for the pergola (and the kitchen extension) including plywood. Then Raincoat Roofing Systems will be invited to make the definitive measurements for the roof and submit their final quote. The provisional quote of 8765 GH Cedis for materials and installation is likely to be lower as discussed with you earlier. Expect next message and photos.
Well the photos did come through not long after.
For those not familiar with concrete curing, it plays an important role on strength development and durability of the concrete structure. Curing takes place immediately after concrete placing and finishing, and involves maintenance of desired moisture and temperature conditions, both at depth and near the surface, for extended periods of time. After concrete is placed, the concrete increases in strength quickly for a period of 3-7 days. Concrete which is moist cured for 7 days is about 50% stronger than uncured concrete.
In our case the builders recommended a period of 14 days to allow the concrete to cure. The curing time is dependent on the nature of concrete works. Simple concrete flooring in a home may cure within 3 days but the more substantive the works the longer the concrete curing time in out part of the world take into into account our average temperatures.
