Cast-in-place concrete (also called site-cast concrete) on of the housing system used in the Philippines is concrete that is poured and cured directly at the construction site, inside temporary molds called formwork.

Instead of manufacturing concrete parts in a factory (like precast), everything is done on-site — from placing reinforcement bars (rebar) to pouring and curing.

Structural foundation works showing dense rebar layout before concrete placement.

 Basic Process of cast-in-place as one of the housing systems in the Philippines.

1. Formwork Installation – Wood, steel, or aluminum molds are set up.

2. Rebar Placement – Steel reinforcement is installed for strength.

3. Concrete Pouring – Fresh concrete is poured into the forms.

4. Vibration – Removes air pockets.

5. Curing – Concrete hardens over 7–28 days.

6. Form Removal – Forms are stripped after initial strength gain.

Precast concrete wall panels delivered by trailer truck and lifted by crane for installation at construction site.

Precast concrete is concrete that is cast, cured, and finished in a controlled factory environment, then transported to the construction site for installation.

This is different from cast-in-place concrete, which is poured and cured directly on-site.

Why Precast Concrete is Used?

1️⃣Better Quality Control

Because it’s made in a factory, temperature, moisture, and curing time are controlled. This results in:

• Higher strength

• More consistent finish

• Fewer defects

  
  

2️⃣ Faster Construction

Since components are ready-made:

• Installation is quick

• Less on-site labor

• Reduced construction time

  
  

3️⃣ Cost Efficiency

• Less material waste

• Lower labor costs

• Faster project turnover

  
  

4️⃣ Strong and Durable

CHB Construction (Concrete Hollow Block Construction)

CHB construction means building walls using Concrete Hollow Blocks (CHB). In the Philippines, this is the most common method for residential houses, perimeter fences, and small buildings.

What is CHB?

Concrete Hollow Blocks are rectangular blocks made of:

• Cement

• Sand

• Gravel (fine aggregates)

• Water

  
  

They have hollow cores to:

• Reduce weight

• Improve insulation

• Allow steel bars (rebars) and concrete filling for strength

Standard CHB Sizes (PH setting)

Common thickness:

• 4 inches (100mm) – interior partitions

• 5 inches (125mm) – light load walls

• 6 inches (150mm) – exterior/load bearing

• 8 inches (200mm) – heavy structural walls

  
  

Typical dimension:

• 40 cm length

• 20 cm height

Basic Steps in CHB Construction

1️⃣ Layout & Foundation

• Mark wall lines

• Build concrete footing

• Install vertical rebars (starter bars)

2️⃣ Block Laying

• Apply mortar (cement + sand mix)

• Align blocks using level and string line

• Maintain consistent mortar joints (10mm typical)

3️⃣ Reinforcement

• Insert vertical and horizontal rebars

• Fill hollow cores with concrete (grouting)

4️⃣ Plastering

• Apply cement plaster finish

• Smooth and prepare for paint

Typical Mortar & Concrete Mix

• Mortar: 1 cement : 3 sand

• Structural concrete: 1 cement : 2 sand : 3 gravel

  
  

(Actual mix depends on structural engineer’s design.)

 Advantages of CHB Construction

✅ Affordable

✅ Easy to source materials

✅ Fire-resistant

✅ Durable

✅ Good sound barrier

Common Problems (If Poorly Done)

⚠️ Cracks due to:

• Weak mortar mix

• Poor curing

• Lack of reinforcement

• No control joints

⚠️ Hollow blocks not fully grouted

⚠️ Misaligned walls

Type	Cost	Strength	Speed
CHB	Moderate	Strong (if reinforced)	Medium
AAC Blocks	Higher	Lightweight	Fast
Precast Panels	Higher	Strong	Very Fast
