“…As noted in (Monteiro andFreire 2010, Bribián et al 2011) the use of firing manufacturing processes leads to considerably high embodied energy values. Many studies emphasize on the energy savings achieved when using unfired earth instead of ceramics (Pacheco-Torgal and Jalali 2012, Shukla et al 2009, Reddy and Jagadish 2003, Udawattha and Halwatura 2016, Chrysostomou et al 2015. However, questions are raised regarding the suitability of such mixtures for the production of load-bearing masonry units because unfired earth has low strength and is susceptible to moisture induced damage.…”

The present study is part of a wider research program, which aims at the development of an innovative masonry construction system that integrates both environmental passive strategies and high energy efficiency. The paper focuses on the parametric computational investigation of the proposed system's basic modular construction component. The thermal performance achieved by alternative geometries of the masonry unit, as well as the use of different constituent materials and insulation fillings, are further examined. The optimum solutions, in terms of thermal performance, were achieved by performing a series of numerical heat flux analyses on alternative proposals, arising from the combination of the above features. Furthermore, the environmental impact, associated with the construction system, is assessed by estimating the total embodied energy of the modular component. It is concluded that the proposed system's thermal performance relies primarily on the characteristics of the constituent mixture composing the modular masonry unit, the geometry of the unit and the use of insulation. In terms of environmental impact, both the constituent mixture used, and the type of insulation material installed, have a considerable impact on the end-product's total embodied energy.

“…Kumanayake et al [17] and Nawarathna et al [50] have introduced two conceptual methodologies to estimate EC in the Sri Lankan context, and Pooliyadda [51] has carried out work to assess the embodied energy (EE) (energy associated with extraction of raw resources, processing materials, assembling product components, transportation, construction, maintenance and repair, deconstruction and disposal of materials) and related EC content of widely used building materials in Sri Lanka. Jayasinghe [52] and Udawaththa and Halwatura [53] have also conducted investigations around selected building materials, but their contents have been limited only to EE content. Reasons for the slow uptake of EC estimations have been investigated by Nawarathna et al [18], and the perceptions of building professionals on EC strategies have been examined by Abeydeera et al [54].…”

Materials are the most important component of building construction. The demands of construction material are increasing day by day significantly. This demand is increasing the material prices and scarcity of material in construction industry. To achieve economical and eco-friendly criteria naturally occurring material is selected. Clay is a natural material and it can be available easily. This paper interprets the experimental investigation on strength of concrete using clay as a partial replacement to binder content (cement) in concrete. The replacement percentages are grouped as 0%, 10%, 20%, 30%, 40% of clay and 5% of hydrated lime with cement in each series in M25 grade of concrete. To achieve the pozzolanic property of clay hydrated lime was added. Different tests are performed to determine the optimum percentage of clay as a replacement for binder content (cement) in concrete. The Compressive strength test, split tensile strength test and flexural strength test were performed on the specimens. Total 90 cubes of size 150 mm were prepared for compressive strength test, 30 cylinders of 150 mm diameter and 300 mm height were prepared for split tensile strength test and 30 beams of size 150 mm x 150 mm x 1000 mm were prepared to carry out the flexural strength test. The results are compared to find the ideal proportion of clay as a replacement for cement. It is found that 10% replacement with 5% hydrated lime gives satisfactory results.
