Rising property rates have made it imperative for builders and developers to look out for ways to use the available space effectively. Conventionally-in any housing structure-around 30-40 per cent of the space on which the structure is built is lost to walls and supporting pillars. It is a loss to both the developers and to the home buyers. Modern construction materials such as Flyocrete AAC blocks are here to rescue both. Yuvraj Patil demonstrates to ICR how these blocks can save space and do a lot more.

Flyocrete´s autoclaved aerated concrete (AAC) blocks are manufactured from fly ash. The fly ash used is a waste from thermal power. Use of fly ash in making AAC blocks save a lot of soil. Bricks on other hand require fertile soil, which is an important resource. Brick manufacturing also leads production of carbon dioxide. From the process of manufacturing till the end use, Flyocrete AAC saves natural resources. Apart from being a green product it also has several other advantages, including:

Lightweight: Oven-dry Flyocrete AAC blocks have a density between 551 to 650 Kg/cum making them 1/3 in thickness than brick and 1/4 that of concrete. So more material can be packed in a truck

for a given structure. It helps in reduction of transport cost as well as the fuel consumed. It is lightweight and leads to reduction of the depth of foundations, sizes of the structural units, saving the cost of cement, steel, coarse aggregate, fine aggregates required for concrete structure. It is suitable for the structures that are erected on low bearing soil, marshy lands, and is useful for all types of residential, commercial, industrial and multi-storeyed projects. This opens avenues for using additional FSI/TDR on existing buildings/societies

Thermal insulation: Its low thermal conductivity leads to saving on energy consumption for heating as well as cooling, suitable as insulating material for steel works, boilers, furnaces, heat exchangers, and oven in different P2 industries, forges. It is also suitable and economical for hotels, malls, multiplexes and hospitals, and all types of commercial projects where air conditioners are used.

Fire resistant: Flyocrete AAC has an extremely high fire rating of at least four hours (200 mm) and more. Due to its high fire resistance, it is useful for the construction of fire wall of lift room/walls of hazardous chemical, paint storage rooms, etc. in textile industries and cotton mills where there is a danger of fire hazard.

High strength to weight ratio: Flyocrete AAC products have strength to weight ratio between 18 to 22 against 16 for the concrete of grade M150. This means thinner walls and thinner pillars can be constructed with Flyocrete. It also means more carpet area for developers to sell.

High dimension accuracy and uniform surface: Due to high dimensional accuracy, it is extremely easy to install. It requires less cement mortar for joining. The uniform and flat surface requires very less plastering material Water penetration: Flyocrete block structures are of closed cells hence there is very little capillary action. The high surface activity allows faster evaporation rates. So the problems of water seepage are minimal with the fly ash-based product. High workability: Flyocrete AAC can be easily cut sawed drilled, nailed, milled like wood, making it a comfortable workable product than bricks, concrete blocks and fly ash bricks.

Cement Makers’ Margins To Fall Rs 50-75 Per Tonne Amid West Asia Conflict

Crisil Sees Margins Easing Despite Steady Demand

Published

Crisil said operating margins of Indian cement manufacturers are expected to decline by Rs 50-75 per tonne (t) this fiscal to Rs 925-950 per t due to higher input costs triggered by the West Asia conflict. The analysis covered 18 cement companies accounting for nearly 90 per cent of India’s domestic cement capacity and noted margins had improved sharply to around Rs 1,000 per t in fiscal 2026.

Crisil noted that the reduction would be driven mainly by higher power and fuel costs, which account for about 30 per cent of total costs, as petcoke and imported coal prices have surged amid geopolitical uncertainties. Freight costs, which account for about a quarter of total costs, are also expected to remain elevated because of higher diesel prices. The impact on profitability is likely to be more pronounced in the first half of the fiscal year before easing commodity prices moderate cost pressures later.

The rating agency said steady domestic demand and strong balance sheets should keep credit profiles stable despite the moderation in margins. Green energy currently accounts for 35-40 per cent of the sector’s total electricity consumption and is expected to partly cushion higher energy costs. Operating cash flows are likely to remain resilient, supported by projected 6-7 per cent growth in cement demand this fiscal.

Crisil highlighted that demand growth will be driven primarily by infrastructure spending, which meets about one-third of sector consumption, and by a nearly 18 per cent higher budgetary allocation for core ministries that should support project execution. Weaker rural housing demand amid pressure on agricultural incomes from a possible below-average monsoon may be offset by improved urban housing demand supported by favourable home-loan rates and a strong pipeline of Pradhan Mantri Awas Yojana-Urban projects. Ongoing capacity additions will keep capital expenditure elevated and may lift net debt to EBITDA to between 1.2 and 1.4 times from around 1.0 time last fiscal, though ratios are expected to remain healthy.

UltraTech Cement’s board of directors has approved raising Rs 5,000 crore (Rs 50 bn) through non?convertible debentures issued in rupees.

The finance committee cleared a proposal to issue up to 500,000 fully paid, unsecured, listed, rated, redeemable, rupee?denominated, non?convertible, non?cumulative debentures of Rs 1 lakh each (Rs 0.1 mn each), aggregating to the Rs 5,000 crore programme.

As of June 2026 the firm reported net debt of Rs 15,875 crore (Rs 158.75 bn) and said its capacity expansion projects under execution are backed by capital expenditure of about Rs 17,000 crore (Rs 170 bn) over the next two to two?and?a?half years.

UltraTech spent Rs 9,500 crore (Rs 95 bn) on capital expenditure in financial year 2026 and in April the group crossed 200.1 mn tonnes per annum of domestic grey cement capacity and 205.5 mn tonnes per annum of global capacity.

The chief financial officer indicated the company would take consolidated capacity beyond 242 mn tonnes per annum, with grey cement capacity reaching 212.7 mn tonnes per annum by the end of financial year 2027. He noted the net debt?to?earnings before interest, taxes, depreciation and amortisation ratio stood at 0.87 times as of June 2026 and the company was confident of ending financial year 2027 with the ratio below one time.

In the first quarter of financial year 2026?27 UltraTech’s net profit attributable to owners rose 16.8 per cent year?on?year to Rs 2,599.3 crore (Rs 25.993 bn) and revenue from operations increased 15.9 per cent to Rs 24,648.20 crore (Rs 246.482 bn). The board approval is expected to complement internal cash flows as the company advances its expansion programme.

Andhra Pradesh Education and IT Minister Nara Lokesh on Wednesday laid the foundation stone for the Line-2 expansion of Dalmia Bharat Cement at Chinnakomerla village in Mylavaram Mandal in Kadapa district. The project carries an investment of Rs 31 billion (bn) and is slated for completion by the third quarter of the financial year 2028. The expansion is intended to boost industrial growth and employment generation across the Rayalaseema region.

Once commissioned, the Kadapa facility will become Dalmia Bharat’s largest integrated cement manufacturing ecosystem in southern India, creating over 1,000 direct and indirect jobs and opening new business avenues for regional micro, small and medium enterprises and transport operators. Lokesh said the expansion signalled growing corporate confidence in the state and reflected the practical ease of doing business that secured repeat investment.

He placed the project within the government’s wider economic targets and recalled the Yuvagalam padayatra commitment to generate two million (mn) jobs within five years, noting that the state would cultivate talent while industry created opportunities. Lokesh highlighted Andhra Pradesh’s competitive pursuit of major manufacturing accounts, mentioning past successes and a personal initiative to engage global investors when persuading them to anchor expansion in the state.

The plant will leverage Kadapa’s abundant limestone reserves to scale production and sustainability. Clinker capacity is planned to rise from two point five million tonnes per annum (mn tpa) to six point one mn tpa, while overall cement output will increase from three point six mn tpa to nine point six mn tpa. The unit is designed to operate on over eighty per cent renewable energy and deploy waste heat recovery, zero liquid discharge, water recycling and advanced AI systems to optimise efficiency. Industries Minister TG Bharat, BC Welfare Minister S. Savitha and Jammalamadugu MLA C. Adinarayana Reddy attended the ceremony.
