State-of-the-art concrete mixing tower from Liebherr

The Betomat holds up to 600 m? of stone in nine silo chambers. The mixing tower is fed with aggregates via two charging hoppers and a powerful bucket elevator with an hourly output of 200 m?/hour.

One of Austria’s most modern concrete mixing plants has been proving its worth since spring 2019. The Liebherr Betomat-type mixing tower was optimally adapted to customer requirements. With the new mixing tower, the Froschl Beton Company is ideally positioned for the future.

The Froschl Beton Company has been supplying construction sites in the Innsbruck area (Austria) with ready-mix concrete for many years. Their 45-year-old mixing plant was technically obsolete and no longer met the standards of today. The wishes and requirements for the replacement purchase were high: Today and in the future, it was supposed to cover the entire concrete logistics chain and deliver flawless concrete efficiently and flexibly.

After an extensive planning phase, Liebherr’s Betomat concept was chosen because it enables the operation of two completely separate mixing plants within one mixing tower. The compact design of the two weighing and mixing lines as well as the Liebherr quality and service were compelling.

The Betomat holds up to 600 m of stone in nine silo chambers. The mixing tower is fed with aggregates via two charging hoppers and a powerful bucket elevator with an hourly output of 200 m?/hour. The plant has seven silos for a binder supply of around 840 tonnes.

The new mixing plant is equipped with two mixer systems: a ring-pan mixer with agitator system and a double-shaft mixer. This means that normal standard concretes as well as high-performance and special concretes can be produced very efficiently. When in operation with both mixer systems, the plant achieves a possible output of around 160 m? of compacted fresh concrete per hour. The tower is equipped with two lanes. Thanks to the separate weighing lines, two vehicles can be loaded simultaneously with different types of concrete – making the mixing plant highly efficient and flexible.

The environment and recycling also play an important role at Froschl Beton. For environmentally-friendly operation, the housing and exhaust air filter systems reduce dust emissions. Noise emissions are also minimised. Residual concrete quantities from the truck mixer and plant cleaning as well as re-concrete quantities are processed in the LRS 908 residual concrete recycling plant. Washed-out material and residual water can be returned to concrete production. This enables considerable cost and material savings.

The longevity of the plant is ensured not only by high-quality components but also by a precisely fitting steel construction from the Liebherr plant in Bad Schussenried. To ensure smooth operation even during the cold winter months, the entire plant is insulated with a 100 mm insulated wall and equipped with heating.

The need of present time is stronger buildings, industrial or common utility buildings, such as Malls, Railway stations, hospitals, offices, bridges etc. For this, there is need of long durable, tough and stable concrete, which could stand under normal and seismic conditions. Tough railway bridges are required for bullet trains to pass without any damage. Railway tunnels, sea-links, coastal roads, bridges and multistorey buildings, are the need of the hour. The question comes, is the normal cement called OPC is sufficient to take care of such requirements or better combination of cements and sand mixtures is required?

Introduction

A good stable building structure can be made with a good quality of cement+sand+water system. Its quality can be enhanced by keeping the density of admixture higher (varies from 30 in normal buildings to bridges etc to 80). Further enhancement in the properties of various cements admixtures is made by adding several additives which give additional strength, waterproofing, flexibility etc. These are called construction chemicals…

The National Council for Cement and Building Materials (NCB) has signed a memorandum of understanding with a leading cement manufacturer to strengthen skill development and capacity building in the construction sector. The agreement was formalised at NCB premises in Ballabgarh and was signed by the Director General of NCB, Dr L. P. Singh, and the head of technical services at UltraTech Cement Limited, Er Rahul Goel. The collaboration seeks to bring institutional resources and industry expertise into a structured national training effort.

The partnership will deliver structured training and certification programmes across the country aimed at enhancing the capabilities of civil engineers, ready?mix concrete (RMC) professionals, contractors, construction workers and masons. Programme curricula will cover material quality testing, concrete mix proportioning, durability assessment and sustainable construction practices to support improved construction outcomes. Emphasis is to be placed on standardised assessment and certification to raise practice levels across diverse construction roles.

Practical learning elements will include workshops, site demonstrations, technical seminars and exposure visits to plants and RMC facilities to strengthen applied skills and on?site decision making. The Director General indicated confidence that a large number of professionals and workers would be trained over the next three to five years under the initiative. The partnership is designed to complement flagship government schemes such as the Skill India Mission and to align training outputs with national infrastructure priorities.

By combining the council’s technical mandate with industry experience, the initiative aims to develop a more skilled and quality?conscious workforce capable of meeting rising demand in infrastructure and housing. NCB will continue to coordinate programme delivery and quality assurance while industry partners provide practical exposure and technical inputs. The collaboration is expected to support long?term capacity building and more sustainable construction practices nationwide.

JSW Cement has strengthened its national presence by commencing production at its greenfield integrated cement plant in Nagaur, Rajasthan, marking its entry into the north Indian market.

With this commissioning, the company’s installed grinding capacity has increased to 24.1 MTPA, while total clinker capacity, including its joint venture operations, stands at 9.74 MTPA.

The Nagaur facility comprises a 3.30 MTPA clinkerisation unit and a 2.50 MTPA cement grinding unit, with an additional 1.00 MTPA grinding capacity currently under development. Strategically located, the plant is positioned to serve high-growth markets across Rajasthan, Haryana, Punjab and the NCR.

The project has been funded through a mix of equity and long-term debt, with Rs 800 crore allocated from IPO proceeds towards part-financing the unit.

Parth Jindal, Managing Director, JSW Cement, stated that the commissioning marks a key milestone in the company’s ambition to become a pan-India player. He added that the project was completed within 21 months and positions the company to achieve its targeted capacity of 41.85 MTPA by FY29.

Nilesh Narwekar, CEO, JSW Cement, highlighted that the expansion aligns with the company’s strategy to tap into rapidly growing northern markets driven by infrastructure development. He noted that the company remains focused on delivering high-quality, eco-friendly cement solutions while progressing towards its long-term capacity goal of 60 MTPA.

The Nagaur plant has been designed with sustainability features, including co-processing of alternative fuels and a 7 km overland belt conveyor for limestone transport to reduce road emissions. The facility will also incorporate a 16 MW Waste Heat Recovery System to improve energy efficiency and lower its carbon footprint.

JSW Cement, part of the JSW Group, operates across the building materials value chain and currently has eight plants across India, along with a clinker unit in the UAE through its joint venture.
