What is ¾ Stone, and Why is it Used in Concrete Production?

**¾ Stone** is one of the most commonly used materials in structural concrete production.

**What is ¾ Stone?**

¾ stone, or “Three-Quarter Stone,” is construction stone approximately 19mm in size, obtained by quarrying and sorting stone by size.

Key properties:

– High strength

– Good compressive resistance

– Durable

– Appropriate size for concrete mixing

**Uses of ¾ Stone in Construction**

– **Building structural work:** Columns, beams, floors, foundations

– **Roads and infrastructure:** Concrete roads, bridges, large-scale infrastructure structures

– **General construction:** Concrete floor paving, parking lot construction, small structures

**Why Use ¾ Stone in Concrete Production?**

– Increases concrete strength

– Helps concrete have a stable structure

– Reduces concrete cracking

**Standards for Concrete Stone**

– Stone size

– Material cleanliness

– FM (Fineness Modulus) value

– Contamination level
