The Construction of Economic Green Buildings in Sinai and Suez Canal Zone Using Compressed Stabilized Earth Technique

Wael Mohamed Adel Tawfik Abdel-latif
Currently, there are several technologies applied in many societies to improve the
use of the environmental resources such as the use of soil with some binders in the
construction of buildings, and the usage of the stabilized earth architecture technique by new urban communities. One of the advantages of these buildings is that they make good use of the environment and save energy and expenditure.
This project deals with the use of the sandy soil which resulted from the excavation of the buildings. It also targets the design and building of whole low energy, ecological, and low-cost green building/villages in the future projects in Sinai and Suez Canal zone, using stabilized earth architecture. The sandy soil under study is that of the sand on the east side of the Suez Canal in Sinai which is a by-product of the dry excavation and wet drilling of the canal.
This paper showed that passive and energy efficient techniques incorporated in
building designs can reduce the electricity requirements. The most effective
parameter is the thermal efficiency of building envelope and blocking sun rays.
The available renewable energy systems can meet parts of building loads. Thermal
bridges are not so common in the bearing wall construction method.
Herein in this paper, several specimens were collected from different sites in
Elferdan and Serapum in Sinai (Suez canal zone) along the east side of the Suez Canal to investigate the suitability of stabilizing this soil for the production of compressed earth blocks for low-cost ecologic building construction. Several tests, e.g., sieve analysis and the proctor test, were made of the specimens. The results showed that the ratio of salts, chlorides and sulfates were low. In addition, the specimens collected sieve analysis ranged from coarse to fine sand.
Stabilizing the materials resulted from the by-production in the industry can be used for minimizing the coast of compressed stabilized earth buildings with high engineering properties.
Experiments on the produced compressed stabilized earth bricks (CSEB) with different level of stabilizing agent (by-product materials) were made using one of the specimens collected from Elferdan zone. The results showed that the 35% CKD ratio of sand weight can be considered as the optimum CKD content; which provides the best properties for the admixture as long as the percentages of cement (OPC) and the fiber-reinforced polymer (FRP) are 5% and 0.07% of sand weight, respectively.
The rest of this research will be completed in the next parts, which includes finding more mechanical, engineering, and thermal properties of the produced CSEB.
