CEILING – CONCRETE SLAB DRY KITCHEN AREA
Concrete Slab as ceiling
Figure 1.1
Figure 1.2
Reinforced concrete slab is a crucial structural element that is used to provide flat surfaces for floors and ceilings. As shown in Figure 1.2 and Figure 1.3, it can clearly be seen that it is a two-way slab as it sits on beams in two directions. Figure 1.3
Two-Way Slab
Two-way slab is a slab supported by beams on all the four sides and the loads are carried by the supports along with both directions. So, the main reinforcement is provided in both sides along both the directions due to bending occurring on both sides.

Material Characteristic, Safety, Comfort & Aesthetic, Concrete Slab Concrete slab is at both economic and low maintenance cost as it is one of the most common structure used in construction of houses. It is a very durable material, high in compressive strength but low in tensile strength. As it is a two-way slab, the cost of formwork is higher because additional formworks for the beam is needed hence why to save cost, it was used as a part of the ceiling with white epoxy paint finish. Epoxy Paint Epoxy paint is suitable to be used for this ceiling as it is a tough and hardwearing water-based paint. White epoxy paint was used for the ceiling to match the walls and to give the room a simple, clean, spacious and open look.
Safety Concrete can be fire resistance therefore if any fire occurs from the wet kitchen area, it will prevent it from quickly spreading throughout the whole house. It is can also reduce acoustic performance in terms of impact noises. Aesthetics
Although having exposed wiring and piping as shown in Figure 1.2 and Figure 1.4 may be less aesthetically pleasing, any maintenance needed can be accessed at ease. Spalling Concrete In Figure 1.5, it is evident that spalling of concrete may occur overtime as a result in corroding of steel bars embedded in the concrete slab which causes concrete cover to crack and bulge. If it is not treated correctly, it may be harmful when bits and pieces of the concrete cover starts to fall off the ceiling. How to Prevent? Preventions method can be taken to account by painting ceilings regularly, sealing cracks and holes regularly and ensure enough ventilation.
How to Repair?
1. Remove all the spalled concrete to expose corroded steel bars.
2. Scrape and clean the exposed steel bars and use a wire brush to remove any rust. 3. Apply 2 coats of anti-rust paint to the steel bars.
4. Apply a bonding agent to the affected surface to ensure proper adhesion. 5. Patch the hacked area using polymer modified cement mortar.
6. Paint over the patched area with white epoxy paint to match the existing ceiling.

Construct a temporary structure using struts, beams and shuttering below
the slab position. 2
Build the formwork on top of the structure to hold the concrete in place.
3
Assemble reinforcements as indicated by building engineer guidelines.
4
Pour concrete in-situ into the formwork by using a boomed concrete pump.
5
Let the concrete cure for 10 – 28 days while keeping it wet and frost-free to
prevent cracking and all building activities must not take place for 10 days. Remove formworks once the concrete has cured and reached the correct strength of the supporting structure.
Paint Finishing 6
Sand concrete slab to remove bumps and uneven surfaces as sealer and
paint won’t adhere to a dirty surface. 7
Ensure that surface is absolutely sry before using a long-handled paint
roller to apply a concrete sealer to the ceiling. Leave it to dry for 2 – 8 hours. 8
Use the long-handled paint roller to apply 2-3 coats of white epoxy paint,
which will adhere to the ceiling and will provide a hard surface that won’t be easily chipped or scratched. Let it dry a day between each coat.

CEILING – SUSPENDED CEILING DINING AREA
Suspended Ceiling – Exposed Grid
Figure 1.1
Figure 1.2
Figure 1.3
Figure 1.4
Suspended ceilings are secondary ceilings suspended from the structural floor slab above, creating a void between the underside of the floor slab and the top of the suspended ceiling. As shown in Figure 1.1 and Figure 1.2, it can clearly be seen that it is an exposed grid suspended ceiling system. The installation method of this particular ceiling is with timber joist, old cellulose ceiling tile nailed onto the timber joist and finished with timber cornice, shown in Figure 1.3 and Figure 1.4.

Material Characteristics, Safety, Comfort & Aesthetic Timber Joist – Pine Wood Pine wood is a coniferous wood that is medium-weight and relatively soft. Its strength and elasticity are good. Pine wood is typically used for building and construction there for it can easily be installed onto the concrete slab as it can be nailed easily. It has high natural moisture content, which can lead to a blue staining of the wood through fungal infection but the physical properties of the wood is unaffected.
Old Cellulose Ceiling Tile Old cellulose ceiling tile is one of the most common ceiling tile used in construction of suspended ceiling for old houses in Brunei. It is a paperbased cellulose mix treated with boric acid to give it fire resistance properties. 1 tile is 3 mm thick and 610 mm by 1220 mm. It is lightweight, very affordable and easy to install as it is nailed directly onto the timber joist. Each tile is also painted over with white flat-latex finish to cover the nails which gives the room a neat finish. Flat-Latex Paint Flat finish coats are latex-based and usually used for ceilings. Therefore, it is suitable to be used on the ceiling because of its latex materials, which is resistant to water damage. There are 2 types of flat-latex paint used, white and black. Aesthetic Not only does it look neat and aesthetically pleasing but it can also hide electrical wirings and piping. Overtime, ceiling tile may turn yellow due to dirty water leaking onto the back of the tile and soaked through the surface causeing discolored stains or due to rust contamination. As it is easy installed, tiles can be detached or replaced when needed to.
