Concrete sand, often overlooked, stands out as a highly recommended option for construction. As a sand manufacturer, we prioritize the quality of your construction, and this blog aims to enlighten you about the benefits of using concrete sand ( C Sand), ensuring you make the right choice for your construction. We hope this blog helps you make wise decisions and achieve successful outcomes.
In this article, we will explore the characteristics, properties, and various applications of Concrete sand, along with information on where to find the best quality C sand in Bangalore. So, let's get started!
What Is C-Sand Or Concrete Sand?
Concrete sand is made by crushing quarried stone to a size that passes completely through a sieve of 0.15 mm - 4.75 mm. Concrete sand is also known by different names, such as crushed sand, coarse sand, and C sand.
Let’s Understand Concrete Sand According to IS Code 383:2016
As per IS Code 383:2016, concrete sand, often referred to as fine aggregate, is a vital component in construction materials. This code defines concrete sand as a crucial ingredient used in the production of concrete, mortars, and grouts. The specifications outlined in IS Code 383 ensure that concrete sand meets stringent quality standards, enhancing construction projects' overall performance, durability, and strength.
Concrete sand is required to have specific characteristics. It should be clean, hard, durable, and free from excessive organic matter such as clay, silt, and other impurities. The particle size distribution of concrete sand is a key consideration, as it directly impacts the workability and strength of concrete mixtures.
Now that we have gained a basic understanding of what Concrete sand is, let us proceed further and broaden our knowledge of C sand.
Demand For C Sand in Karnataka
In Karnataka, there is a high demand for C sand. According to technical specifications, demand is estimated based on its use in concrete. Concrete is a mixture of cement, sand, and aggregates mixed in a 1:2:4 ratio.
In 2012, India's cement production was 248 Mt, and per capita cement consumption was 202 Kg. Based on a 7.7% growth rate, national cement production in 2014 is estimated to be 13 Mt. Using the standard C sand-to-cement ratio in concrete, it is estimated to be 26 Mt2. The estimated demand for C sand will grow between 56 Mt and 81 Mt until 2030, similar to the GDP, which is expected to grow between 5.02% and 7.5% per year in the coming years.

How Is Concrete Sand made or manufactured?
Concrete sand is made by crushing hard stones into small particles ranging from 0.15 mm to 4.75 mm, and it takes place in different stages.
The process of manufacturing C-sand involves four stages, which are as follows:
Stage 1: Jaw Crusher:
The initial stage of sand manufacturing involves crushing larger stones into smaller ones; this is achieved using a jaw crusher.
Stage 2: Cone Crusher:
Output from the jaw crusher will be sent to another crushing process called the cone crusher. It further reduces the size of stones by breaking them into smaller pieces. A cone crusher produces 20 mm aggregate and 12 mm aggregate, along with small sand particles. The outcomes from the cone crusher are flaky and elongated and are not suitable for concrete sand. The 0–5 mm particles produced from the cone crusher are called Dust.
Stage 3: Vertical Shaft Impact:
The flaky and elongated products from the cone crusher will be sent to a vertical shaft impact, which produces superior-quality aggregate by breaking the flaky and elongated aggregates into rounded ones. Through this process, M sand gets produced, which is of size 0 to 5 mm. Although M sand has quality aggregate, it contains silt, which is not suitable for construction. Despite this, few suppliers sell it as C sand in the market at lower prices, but it is not suitable for construction due to the presence of ultra-fine particles.
Stage 4: Hydrocyclone:
VSI output is sent to a sand-washing plant with a hydrocyclone. It removes the silt and other impurities, and the final product is Concrete sand, which is best for construction.
What are the Properties of C Sand?
Particle Size:
The particle size distribution of concrete sand should be well-graded, ranging from 0.15 mm to 4.75 mm, ensuring a balanced mix of fine and coarse particles.
Cleanliness:
Impurities like silt, dust, dirt, and other organic substances should be removed from the sand, and it should be thoroughly washed to remove these substances, improving its strength and durability.
Grading Zone:
The IS code 383:2016 categorizes concrete sand into 4 grading zones, namely: Zone 1, Zone 2, Zone 3, and Zone 4. Each and every zone shows a varied particle size distribution range, allowing for flexibility in concrete mix designs.
Fineness :
The fineness modules of C sand should fall in the range of 2.2 to 3.1, which helps to determine the overall particle size distribution and suitability for concrete applications.
Specific Gravity:
The specific gravity of c sand should range between 2.5 and 2.9, providing insights into its density and suitability for concrete mix.
Silt Content:
Sand should have a minimum or no silt content. Excessive silt will negatively impact the workability and strength of the concrete.
Strength and Durability:
Concrete sand, when used in the correct proportions, contributes to the overall durability, strength, and performance of the concrete mix.
Applications of C-Sand:
Concrete Mix:
Concrete sand is an important component of the strong concrete mix. C sand provides the necessary surface area for the binding material film to adhere and spread. It increases the volume of mortar and the density of concrete. When C sand is combined with cement, water, and aggregates, it produces an efficient and structurally sound concrete mixture that can be used for a variety of applications, such as foundations, slabs, driveways, and structural elements.
Masonry Work:
Concrete sand is widely used in mortar for masonry work, like concrete block laying, bricklaying, and stone installations. Since C sand enhances the bonding properties of the mortar, it ensures the stability and strength of the masonry structures.
Landscaping:
Concrete Sand can be used for pathways, patios, stairs, driveways, etc. Its rough texture allows for adequate drainage, preventing water accumulation and potential damage.
