alite, belite
& clinker
Alite is a key mineral found in Portland cement clinker. It is primarily composed of tricalcium silicate (Ca₃SiO₅) and is responsible for the early strength development in cement due to its rapid hydration properties.
Belite is a mineral found in Portland cement clinker, primarily composed of dicalcium silicate (Ca₂SiO₄). It contributes to the long-term strength development in cement, hydrating more slowly than alite.
alite, belite
& clinker
a ceaseless interplay between progress and decline, an eerie ballad of creation and collapse.
The Northfleet Thames estuary…
…a liminal space where land and water talk about collapse. As one approaches the estuary banks, the first impression is an overwhelming sense of decay and resilience intertwined. The vast expanse of water, ever-shifting and never still, laps at the edges of a landscape scarred by material ambition. Factories and warehouses, hulking and grey, stand sentinel along the shoreline, their façades mottled with the grime of decades. These structures, both monolithic and ephemeral, speak of an industrial past that has left an indelible mark on the environment and the collective memory of the region.
Air once thick with the acrid smell of cement production, a testament to the ceaseless activity within the industrial works that dot the area. Here, clinker — the rough, lumpy precursor to cement — emerges from the kiln, a hardened relic of a process both ancient and modern. It is in the transformation of limestone and clay into this gritty substance that the alchemical nature of industry is laid bare, filling the air with a rhythmic, almost hypnotic noise, a percussive symphony of progress and obsolescence.

Clinker is a solid material produced in the cement kiln as an intermediary product during the manufacturing of Portland cement. It consists of various calcium silicates and other compounds, which are ground to produce cement.

Among the compounds once produced in colossal kilns are belite and alite, minerals whose names evoke a strange, almost poetic quality. Belite, with its slower reaction, symbolizes endurance, a quiet persistence that stands in contrast to the more reactive alite, which represents the rapid setting of cement, and the urgency of modern construction. Together, they embody the dual nature of the Northfleet estuary: a place of slow erosion and rapid change, where the old and the new are forever intertwined.
Walking along the estuary banks, one is struck by the juxtaposition of natural and artificial noise. The gentle lapping of the Thames is punctuated by the relentless grind of machinery, a reminder that even in moments of seeming tranquillity, the forces of industry are ever-present. The noise becomes a backdrop to contemplation, a sonic tapestry that reflects the complex interplay between man and nature.
The buildings themselves, with their crumbling brickwork and rusting steel, bear silent witness to this ongoing dialogue. Each crack and crevice tells a story of neglect and renewal, of human ingenuity and environmental toll. The graffiti that adorns their walls, a burst of colour amidst the grey, serves as a testament to the resilience of life in the face of decay. In this landscape, time seems to fold in on itself, past and present merging in a continuous loop. The ghosts of workers long gone seem to linger in the shadows, their toil and sweat imbued in the very fabric of the buildings they once labored within. The estuary, with its ever-changing tides and steadfast structures, becomes a living chronicle of human task and natural persistence.
