ハイデラバードの都市開発を対象に、コンクリート・レンガ中心の建設を維持しつつ資材面から脱炭素化する方策を検討。GHMC事業やORR回廊、HITEC City、高層住宅に関わる9つの資材課題を特定し、各々の解決策を提示する。フライアッシュ30%代替でセメント由来排出を約29%、GGBS50%代替で約46%削減できると試算し、モデル仕様・パイロット・36カ月ロードマップを提案する。
English
This paper examines how Hyderabad's conventional concrete-and-brick construction can be made greener without abandoning it, identifying nine material-related problems across GHMC works, the ORR corridor, HITEC City and high-rise housing, each with a proposed solution. Illustrative calculations show 30% fly-ash substitution cuts cement-related emissions ~29% and 50% GGBS substitution ~46%. It proposes a model specification, pilot projects with performance indicators, and a 36-month roadmap.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本では建設資材のエンボディドカーボンはScope 3カテゴリ1・3として開示対象になりつつあり、公共発注での低炭素資材調達や積算基準の見直しはSSBJ対応や自治体グリーン調達の実務に示唆を与える。
In the global GX context
Embodied carbon in construction materials is increasingly captured under Scope 3 and addressed by green public procurement rules in the EU and elsewhere; this paper's procurement and Schedule of Rates reform angle speaks to how disclosure and purchasing standards can drive material substitution in emerging-market cities.
👥 読者別の含意
🔬研究者:建設資材のエンボディドカーボン削減と公共調達改革を結びつける実務志向の枠組みとして参照できる。
🏢実務担当者:セメント代替材（フライアッシュ・GGBS）の仕様採用と調達基準改革が排出削減とコストにどう効くかの目安になる。
🏛政策担当者:公共事業の積算・調達基準に低炭素資材要件を組み込む際の設計とロードマップの参考になる。
📄 Abstract（原文）
Hyderabad is expanding rapidly through large public programmes and high-rise development, yet most green-city initiatives address land, water and energy and give limited attention to the construction materials that determine a structure’s embodied carbon, durability and waste footprint. This paper examines how conventional concrete-and-brick construction can be made substantially greener without abandoning it. Through a desk-based review of Indian standards, published literature, State policy announcements and project data, nine material-related problems affecting Greater Hyderabad Municipal Corporation (GHMC) works, the Outer Ring Road (ORR) corridor, HITEC City and tall residential buildings are identified, and a specific solution is proposed for each. The solutions cover cement and concrete mix strategies, recycled aggregates from construction and demolition (C&D) waste, lightweight walling, cool and permeable surfaces, durability measures, road-corridor materials, procurement and Schedule of Rates reform, incentives and verification, and supply-chain and skills support. An illustrative calculation shows that, under stated assumptions, replacing 30% of the cement in a concrete mix with fly ash lowers its cement-related emissions by about 29%, and replacing 50% with ground granulated blast-furnace slag (GGBS) lowers them by about 46%. The paper proposes a model specification, pilot projects with defined performance indicators, and a 36-month roadmap.
