GGBS Manufacturer in Gujarat Top Tips to Choose Right GGBS Grade for your Project

Ground granulated blast furnace slag is an important part of your concrete and infrastructure projects. According to the GGBS manufacturer in Gujarat, it provides durability, sustainability and long-term strengths to your infrastructure projects.

However, you will notice that not all the GGBS is built equally and you may want to select the right grade GGBS for the application. The right material can impact the performance and longevity of the construction.

This is true whether you are building a dam or investing in marine structures. The GGBS grade can ensure success of your project. With this guide, you can find the grade that best fits your project.

1.      The first question or issue to understand is what GGBS is and why your GGBS grade matters. GGBS is the by-product of iron production, which is rapidly cooled and dried to create the fine powder. This material is used in supplementary cementitious material within the concrete and it can replace the ordinary Portland cement. The surface area, reactivity and compliance with national/international standards will define the grade of the GGBS. The grade is used to define the setting time, long-term strength, workability and durability of the GGBS.

2.      The GGBS supplier in Gujarat believes that there are definite standards that tend to define the GGBS grade. the standards that define the grades and with it the specifications for GGBS depend on the country and project location. In India, your GGBS should meet the IS 12089 specification. This mentions the GGBS that can be used as part replacement for Portland cement within the concrete. The minimum blain fineness is about 275 m2/kg. For UK and EU, you need to follow BS EN 15167 certification that defines the GGBS you can use within concrete and mortar. If you are in USA, ASTM C989 is the most important certification. There are three grades for this certification- 80, 100 and 120. Grade 80 is considered low reactive while Grade 120 is highly reactive with early strength. When you define the grade of the GGBS, it will help the engineer and contractor choose the right one that meets the demands of their project.

3.      There are several factors to consider when you are choosing the right grade for GGBS. According to the GGBS manufacturer in Gujarat, you should look at the project type and its structural requirements before getting started. The mass concrete is known for reducing hydration heat and prevents thermal cracking. It is a moderate reactivity grade. similarly, high-strength and precast concrete is useful in ensuring early strength. Lastly, if you are planning marine and coastal structures, it can enhance the performance. You should also know that GGBS can typically slow down the setting time for concrete. you should use higher grades in case you plan to ensure faster setting or strength. You can also adjust the cement to GGBS ratio to balance the setting and workability of the concrete. Lastly, you must considered cement replacement ratio to maintain the strength of the concrete and its setting time.

4.      You must consider the workability and finish requirements for better finish, according to the GGBS supplier in Gujarat.
