إن الهدف من هذا البحث هو دراسة تأثير رماد الخشب في الخصائص الريولوجية للمونة ذاتية التوضع (SCM) من خلال تشكيل عدة خلطات بنسب مختلفة من الرماد و مع نوعين مختلفين من الاسمنت و باستخدام ثلاثة أنواع من الملدنات و دراسة تأثير ذلك في قطر الانتشار و في إجهاد الخضوع لهذه الخلطات.
The objective of this research is to study the effect of wood ash in rheological properties of Self – compacting mortar (SCM). By implemented some mixtures with different percentage from wood ash with two kinds of cement and three kinds of super plasticizer and study the effect in slump flow and yield stress to this mixtures.

Asphalt plays the role of envelope and bonding in asphalt gable, and is exposed to a range
of changes that start from the stage of production of asphalt mosses to the stage of
investment under the influence of traffic loads and weather factors. The
aim of this
research is to investigate the possibility of using polypropylene polymer to modify the
properties of the asphalt binder and to increase its resistance to high temperatures and
different climatic conditions by modifying the asphalt by adding polypropylene by (1, 2, 3,
4, 6, 8%) And perform traditional tests on modified asphalt samples . Using Thin film oven
test RTFOT test to perform the short-term Aging on normal and modified asphalt samples,
heat loss, residual Penetration and aging index, And conduct a structural composition test
to determine asphalt compounds. The results of the study showed that the values of
Penetration tend to decrease with the increase of the percentage of addition while the
degree of Softening point. The results showed increased resistance of asphalt modified to
the thermal conditions. The optimum percentage of polypropylene is 3% Loss on heat at
the lowest level.
It was investigated in this study the influence of
Carboxymethylcellolose (CMC) solution concentration,
temperature, and pH on the rheological properties according to the
shear stress as function of shear rate. Experimental results show that
shea
r stress increase at all operational conditions as the shear rate
increase. When the shear rate is constant, the shear stress increases
also with the increasing of both concentration and pH as well as the
decreasing of temperature.
The results showed the possibility of getting at a wide rang of board with different properties, and all investigated percentage had special properties which to use in industrial application, also the result showed the possibility to produce these bo
ard without pretreatment of particles wood or without addition any virgin plastic to RLDPE
The results showed the possibility of getting of a wide spectrum of boards with different properties, and all studied percentages had special properties which allow them to use in industrial application, also the result showed the possibility to produce these boards without treatment of the wood particles or without addition any virgin plastic to RLDPE
The ideal selection of raw materials in manufacturing process is a very important step to
develop this process and to improve the product. For this purpose, we search for initial
parameters to guide us in using clay materials (wherever it locate) i
n ceramic industry. These
parameters depend on physical properties of clay (Atterberg Limits). We follow experimental
and analytical methods for laboratories tests applied or clay, and for ceramic samples tests. We
deduct initial parameters which determine technical specification values for ceramic product,
and we derived mathematical formulas between clay properties and technical specification for
ceramic product. These parameters and formulas help us to achieve ideal investment for clay
ambushes either as pure raw materials or with suitable additives to reach on acceptable value
for water absorption of ceramic product which, at the end, specify the type of product according
to international specification.
This research study the impact of additions to improve
limestone mortar properties to become comparable to hydraulic
lime which is used in other countries, by using additions relative
to that were used in the old mortar, also used modern additions
like fiber glass to limit unwanted contraction in the use of
limestone mortar, , especially in arid environments.
