dc.description.abstract |
Embodied carbon emissions have been overlooked in the past few decades. As such,
today, the building sector is responsible for 38% of all carbon emissions in the world
greenhouse gas emissions. To overcome the climate crisis, sustainable construction
practices, reducing reliance on carbon insensitive raw materials usage and net-zero
carbon standards are being implemented across the globe. Building with earthen
materials becomes a focal point in sustainable building design practices since its an
environmentally friendly construction practice. Although there are several earth-based
modern construction techniques for walling available in Sri Lanka (such as rammed
earth, mud-concrete), no reliable technique is developed or adopted as a slab system.
Most of the recent earthen constructions are either single-storied or use concrete as
their slab system. Thus, the earthen slab system would be a huge step towards a
structure entirely made of earthen materials.
Here, it is attempted to identify the structural behavior of the doubly curved shell
structure using Finite Element Analysis (FEA) and the possibility of constructing an
earthen slab system using Mud-concrete. It was identified that nearly 50% of cost
reduction can be expected when compared with the reinforced concrete slab systems.
A 1m x1m prototype Mud-concrete slab was constructed to check the potential for
modular construction practice with a square footprint. The masonry mould method was
used as the formwork system by considering the ease of the construction. Shell
thickness of 50mm is the primary structural component, while the non-structural filling
of 50mm from apex was used with the Mud-concrete mixture used as a flat floor
surface. |
