1.	Influence of acrylic coatings and nano-materials on the interfacial, physical, and mechanical properties of limestone-based monuments “Amenemhat II temple as a case study”
The present paper covers the study of limestone consolidants based on acrylic polymer (Paraloid B-72), Ca(OH)2 nanoparticles (Nanolime) and the acrylic polymer mixed with Ca(OH)2 nanoparticles. The experimental study was conducted on limestone samples from El-Ashmunein archaeological area, Minia, Egypt. Some tests were done for studying the behavior of the consolidants used. The main goal of these tests was to ... إقراء المزيد

2.	Alteration parameters affecting the Luxor Avnuxe of the Sphinxes-Egypt, Science of the
Stone alteration in the environment is caused by various extrinsic disintegration agents, besides, their intrinsic properties “mineralogical composition, textures and internal structure”. Therefore, the purpose of the current study was to evaluate the weathering state affecting the Luxor Avenue of the Sphinxes by studying its chemical, mineralogical and physio-mechanical characteristics, in addition to morphological features. Scientific techniques, such as X-ray ... إقراء المزيد

3.	Environmental impacts: Weathering factors, mechanism and forms affected the stone decaying in Petra
The decay of stones in a natural environment is governed by extrinsic and intrinsic factors. Petra is exposed for centuries to the severe climatic conditions especially temperature (T), total monthly rainfall (TMR) and relative humidity (RH). In this regard, there are negative effects that result from these climatic elements on stone; which affect or are based on the chemical characteristics ... إقراء المزيد

Air pollutants and dust affected the artifacts in Luxor museum; one of the most important museums in Egypt and the Middle East. Therefore, the present investigation is concerned with air pollutants and dust that may be affective or catalyst in the deterioration of Luxor museum's artifacts using the following technique: a) The checker of PH used for monitoring and identifying ... إقراء المزيد

Cleaning of architectural bricks using RF plasma "Metallic Stains
RF Plasma is a glow discharge typically generated through using oxygen and hydrogen as the input working gas. In the current study the radio frequency (RF) hydrogen plasma (H2) is used for removing some metallic stains (iron and copper) which affected the historical brick surfaces in Prince Yousef Kamal place. Untreated and treated surfaces were evaluated by OLS, EDX-SEM & ... إقراء المزيد
