|
We received an inquiry from an owner of an apartment in Aoba-ku, Yokohama. Typically, it is common to drill holes in blocks using a core drilling method to install fences. However, since the blocks are old and lack strength, we installed them using gripping hardware and block reinforcement materials. |

Block Reinforcement Work Construction Procedure
1. Existing Concrete Floor Chipping, Block Hole Drilling, Excavation Work
“Concrete floor chipping” refers to the work of removing or demolishing concrete or brick floors and block walls. Since the concrete floor plays an important role as the foundation of the building, the chipping work must be done carefully.
2. Processing and Installation of Block Reinforcement Hardware
3. Concrete Pouring
“Doma-uchi” (土間打ち) refers to the process of pouring concrete onto the floor or ground of a building. Specifically, it is known as “doma-uchi” when concrete is poured and leveled in areas that come into contact with the ground. This process is mainly performed in places where the floor directly touches the ground, such as warehouses, garages, factories, and the first floor of residences.
What is Concrete?
Concrete is one of the materials widely used in modern construction and civil engineering, made by mixing cement, water, sand, and gravel (or crushed stone). This material creates a very strong structure when it hardens and is used in many buildings and infrastructures.
Main Materials of Concrete
Cement
Cement is the main component that determines the strength of concrete. Typically, Portland cement is used. Cement reacts with water to undergo hydration, hardening and solidifying the concrete.
Water
Water is essential for triggering the hydration reaction of cement. If there is too much water, the concrete becomes weak, and if there is too little, it does not mix uniformly.
Sand (Fine Aggregate)
Fine aggregate, such as sand, is used as a filler in concrete, enhancing its density and strength.
Gravel (Coarse Aggregate)
Coarse aggregates like gravel or crushed stone are also included in concrete, contributing to its strength and reducing drying shrinkage.
Properties of Concrete
High Compressive Strength
Concrete is very strong under compressive forces, making it suitable for large structures. Compressive strength is the main source of concrete’s strength.
Low Tensile Strength
While concrete is strong in compression, it is weak under tensile forces. Therefore, “reinforced concrete,” designed to withstand tensile forces using reinforcement materials like rebar, is widely used.
Durability
Concrete is highly durable and has the characteristic of increasing in strength over time. It also has high resistance to climate change and corrosion.
Fire Resistance
Concrete is resistant to high temperatures and is relatively safe even during fires. This is one reason why it has superior fire resistance compared to steel-framed buildings.
Due to its strength, durability, and flexibility, concrete is an essential material that supports the foundation of modern buildings and infrastructure. Buildings made of properly designed and constructed concrete have long-lasting durability, which is why they are widely used.
