Abstract

The increasing number of residents demands the provision of settlement facilities and infrastructure. Limited land is an obstacle to the development in the horizontal direction, especially the use of green open land which will cause land conversion. The limitation of the building height regulated by local regulations, as well as the local wisdom, namely vertical holiness can be a challenge related to the idea of building multi-storey buildings. When you want to enter the lower floors of the building, there is a feeling of doubt because there are other residents on the upper floors who step over. This study aims to reveal the relationship of vertical holiness with multi-storey building design and formulate vertical holiness as an effort to implement it in a design so that it can be accepted by the community. This study uses a methodology to examine the problem by interviewing the stakeholders and filling out the questionnaire, therefore, the relationship between vertical holiness and multi-storey building design can be obtained. The results of the study clearly confirm that there is indeed a correlation between vertical holiness and multi-storey building design. Thus, the design should pay attention to this vertical holiness. The study also encourages that the formulation of vertical holiness should be legally stated in regulation so that it is easily understood and accepted by the community.

Abstract

Waste bricks powder is pozzolan a material which contain silica and alumina activated that could react with the Portland cement (SPI). Compounds content SiO2 + Al2O3 + Fe2O3 bricks powders from Desa Oebelo of 91%. The pozzolan materials pass quality specifications according to ASTM C618 where the amount of compounds SiO2 + Al2O3 + Fe2O3 at least 70%. This research is to use of waste brick powder as a pozzolan material in concrete mixtures. Research on the mechanical properties of concrete with brick powder (SBB) as a partial substitution on the Portland cement (SPI) has been realized using cylindrical specimens of diameter = 150 mm and height = 300mm. The specimens were made by using a proportion, by weight, of 1.0 binder: 2.0 sand: 3.0 crushed stone and water binder ratio of 0.5. The binder was made by a mixture of SPI and SBB. The percentage of SBB in the binder varied: 0%, 10%, 20% and 30% by total weight of the binder. Thegrain distribution of sand and crushed stone were designed according to SNI 03-2834-2000 to meet respectively the gradation zone 2 for fine aggregate and the granules with a maximum diameter of 20 mm for coarse aggregate. The test of concrete mechanical properties included compressive strength, modulus of elasticity and split tensile strength and realized atthe specimen’s age of 28, 56, and 90 days respectively using three specimens for each test.The test result shows that the positive reaction of brick powderas a pozzolanic material can only be noted after the hydration age of 90 days. The development of compressive strength, modulus of elasticity and split tensile strength depend on the percentage of SBB used in the binder. In fact, the use of 10%SBB in the binder produce compressive strength, modulus of elasticity and split tensile strength respectively about 97%, 94%, and 98% compared to those produced using 100% SPI. This interesting performance could be strongly related to the pozzolanic effect of SBB on the long term of hydration.

Abstract

Research on the use of stone dust (SDT) as a partial replacement of Ordinary Portland Cement (OPC) has been carried out by using cylindrical concrete specimens with Ø = 150 mm and h = 300 mm. Specimens were made by using the ratio, in weight, of cementitious material : sand : crushed stone of 1.00 : 1.93 : 2.67. The water cementitious material ratio is of 0.52. The cementitious material is a mixture of OPC and SDT. The percentage of OPC replacement by SDT varied from 0%-25%. The distribution of grains of sand and crushed stone are designed according to SNI 03-2384-2000: gradation zone 2 for fine aggregate and gradation with a maximum diameter of 20 mm for coarse aggregate. The tests of compressive strength, elastic modulus, tensile strength and permeability on the cylindrical specimens were realized at 28 and 56 days. The result indicates that SDT shows a good pozzolanic reactivity in terms of compressive strength, elastic modulus, tensile strength and permeability. Therefore, it can be used as a component of Portland Cement Composite. The development of compressive strength, elastic modulus, tensile strength and permeability of concrete produced with a mixture of OPC and SDT depends on the amount of SDT used in the mixture and hydration time. The pozzolanic effect of SDT can only be seen at the age of 56 days. The optimal use of SDT as a partial replacement of OPC in concrete applications varied from 5%-10%.
