يهدف هذا البحث الى عدم الافراط في استهلاك رمال النهر بالخرسانة لان هذا المزيج القابل للإلحاح من الأسمنت والماء والرمل والحصى الذي يصلب إلى مواد بناء قوية للغاية.حيث كان رمل النهر هو الخيار الأكثر شعبية بالنسبة للمكون الكلي الدقيق للخرسانة سابقا ، لكن الإفراط في استخدام المواد أدى إلى مخاوف بيئية واستنزاف رواسب رمل النهر وزيادة في سعر المادة وهي تتكون من مواد جدران مصنوعة من الرمل الطبيعي الخشن أو غبار الصخور المكسرة الممزوجة بالإسمنت بنسب معينة وماء ، وقوة ضغطها معتدل في الأشكال. نشارة الخشب هو النفايات العضوية الناتجة عن طحن ميكانيكي أو معالجة الأخشاب في مختلف الأشكال والأحجام, وكان في الماضي يستخدم اغلبة كوقود محلي، كذالك لمقارنة خصائص قوة الخرسانة العادية والخرسانة مع غبار المحجر وغبار المنشار, الازدياد لتحقيق الاقتصاد في البناء. فان النطاقات في هذا البحث هو لدراسة تأثير غبار المحجر ونشارة الخشب بالخواص الميكانيكية للخرسانة و لمقارنة قوة الشد الانضغاطية وقوة الانثناء باستخدام غبار المحجر ونشارة الخشب مع الخليط التقليدي.

This research aims to not excessive in the sands of the river consumption concreted because this disposable urgency of the mixture of cement, water, sand and gravel, which hardens into building materials strong Gaah.hat was the sand of the river is the most popular choice for the overall component flour previously for concrete, but excessive use of materials led to environmental concerns and depletion of river sand deposits and an increase in the price of material which is made up of walls of materials made of natural coarse sand or dust mixed with rocks crushed cement and certain proportions of water, and the strength of compressed in a moderate way. Sawdust is organic waste generated by grinding mechanical or wood processing in various shapes and sizes, and it was in the past used mostly as fuel local, Kmalk to compare the characteristics of strength ordinary concrete and concrete with dust quarry and saw dust, increasing to achieve economy in construction.

This research aims not to over-consume the river sand sands with concrete because this urgent mix of cement, water, sand and gravel that hardens into very strong building materials. The material has led to environmental concerns, the depletion of river sand deposits and an increase in the price of the material, consisting of wall materials made of coarse natural sand or broken rock dust mixed with cement in certain proportions and water, and its moderate pressure strength in shapes. Sawdust is organic waste resulting from mechanical grinding or wood processing in various shapes and sizes, and in the past was used mostly as a local fuel, as well as to compare the properties of the strength of ordinary concrete and concrete with quarry dust and saw dust, increasing to achieve construction economy. The scopes in this research are to study the effect of quarry dust and sawdust with the mechanical properties of concrete and to compare the pressure tensile strength and bending strength using quarry dust and sawdust with the traditional mixture.

The purpose of this study is not to over consume river sand concrete, as it is an urgent mixture of cement, water, sand and gravel, solidified into very strong building materials in river sand is an option. For the former concrete aggregate, the most popular ingredient, but the overuse of materials has led to environmental concerns, the price of river sand and materials has increased, which is caused by The shape of natural coarse sand or dust bearing broken rock mixed with water in a certain proportion, with medium compressive strength. Sawdust is the organic waste produced by mechanical grinding or processing of various shapes and sizes of wood. In the past, fillers were used as local fuel, so the strength characteristics of ordinary concrete and concrete were compared with that of quarry dust and sawdust to improve the construction economy. This paper studies the influence of quarry dust and sawdust on the mechanical properties of concrete, and compares the tensile strength, compressibility and bending strength of sawdust and sawdust mixture. Conventional.
