The use of bamboo as building materials has occurred for a long period, especially in a simple construction system. Bamboo can be utilized as a building material due to its advantages. One of the advantages is that bamboo has a significantly low density so  it can reduce the density of concrete whose main material is gravel. Gravel is a natural building material is formed from unconsolidated rock fragments, such as rock pieces or small rocks. Gravel is commonly found in Indonesia because there is a lot of availability. This research aims to utilize local bamboo resources as building materials. Bamboo is used as an alternative substitute for gravel aggregate in the concrete mixing. The research method was experimental laboratory work. The results showed that the use of bamboo as an aggregate can only be used in non-structures, this is because the rate  of absorption of bamboo against water is quite high. While the compressive strength of the concrete produced by  mixing 100 % bamboo aggregate has an average value of 3.09 MPa and mixing 50 % of bamboo has an average value of 6.01 MPa. Therefore, the quality of the concrete cannot be used for building structures, but  only be used in non-structural buildings.

This paper is about Interlocking Stabilized Soil Blocks (ISSB) as developed in Thailand. ISSB are seen as an eco-friendly building material for home building and structures such as water tanks and sanitation facilities. For several decades the Thai R&D Institute TISTR has worked on developing and testing ISSB, which in other countries are called compressed stabilized earth blocks or CSEB. The composition of building blocks and the quality of building structures determine together the structural quality of the house or building. If there is a need for earthquake- and storm resistance, the building blocks and the structures must have specific features. Building stacked houses is an important issue given the growing scarcity of land for housing and the increasing land prices. ISSB is not only applied in Thailand, but also in Cambodia for low-cost housing and in Nepal for home reconstruction after the 2015 earthquake. ISSB or CSEB is also applied in other countries as an alternative building material and technology to replace the use of fired bricks and concrete building blocks for housing. Reducing the use of cement in the materials and structures is important for environmental reasons, but in ISSB/CSEB the use of cement as a stabilizer cannot always be avoided. This is surely the case in areas where earthquakes, heavy storms and floods can occur. Although this paper focuses mainly on technical aspects of sustainable housing and construction, there is also a focus on social sustainability, meaning a strong involvement of local communities in the production of sustainable building materials for walls, newly developed construction technologies, and mutual house and facility construction.

Present World

The present world cannot be imagined without construction industry. On other hand we are not able to prevent impact of construction on the environment due to usage of its key component that is cement, which plays a greater role in the emission of greenhouse gases. Every tonne of Ordinary Portland Cement (OPC) that is produced releases on average a similar amount of CO2into the atmosphere, or in total roughly 6% of all man-made carbon emissions. One of the purposes of research should be to lower the amount of cement during construction without compromising the quality of building structure. Microbial metabolic activities often contribute to selective cementation by biomineralization. In the present study, a novel microbial based low energy green building material based on microbially induced calcium carbonate precipitation (MICP) has been reported that is known as “biocement”. Biocement has enormous potential and usage in building materials and structures with potential to partially replace the cement. The research demonstrates that production of biocement can enhance the durability of building structures in addition to have least impact on the environment.

All human societies seek stability and use of place and material in order to create architectural buildings. One of the most important materials that man used as a building material was natural stone, and in Jordan stone has a special architectural value, as Jordanian architects used it to form a unique architectural style, especially in the capital, Amman. But at the end of the last century and the beginning of the current century, alternative manufactured building materials appeared, and architects began using them for many reasons, including the lack of quality of natural stone and its defects, which resulted in deformation of the architectural facades. The research used remote sensing techniques to know the properties and quality of the stone. This research used the descriptive approach in studying the history of architecture in Jordan and its relationship to limestone, and relied on the analytical survey by obtaining data from satellite images, where they were analyzed and the properties of the stone in the ground were shown. This research aims to preserve the use of natural stone in construction as a building material that has characteristics in sustainability.

Adequate Method

Consideration of the durability of building materials from a thermal fluctuation position is the most difficult, but at the same time the most adequate method now. Since this concept is insensitive to changes in the physical structure, it becomes necessary to consider not only the material, but also the configuration of the structure. This will make it possible to bring the simplified theoretical ideas about the performance of a building material in a structure closer to real conditions. Thus, the aim of the work is to compare the destruction mechanism of PVC sheet elements of solid section and composite section from the thermal fluctuation position. To achieve this goal, the initial data for finding thermal fluctuation constants (durability of PVC plates at non-critical stress) were determined by an experimental method. Based on the initial data, the thermal fluctuation constants for each section were determined by the graphic-analytical method. During the comparative analysis, it is proposed to introduce a coefficient into the Zhurkov’s equation, which will consider the configuration of the section. It was also determined that for PVC sheet elements of composite cross-section in two layers, this coefficient is kc = 2. Considering the configuration of the cross-section when determining the thermal fluctuation dependences will increase the quality of predicting the durability of the building material.
