The entire sanding was carried out under water.
Table 2: The amount of water, water–cement ratio, overflow values ​​of the mixtures and bulk density.
Depending on the water–cement ratio, the number of pores created by the water drying and the bulk density resulting from this factor.
· The required water–cement ratio grew with the increasing content of micronized marble powder

The main professional concepts must be supported by effective urban instruments, implemented at administrative level.
One of the most important problems in Craiova has been the lack of water supply throughout history.
Thus, the fountains of the city take on overwhelming significance for its development, as the water springs have the power to attract the inhabitants equivalent to that of the churches.
Center area historical buildings functions types Interventions on historical monuments and buildings that have been identified as having the highest degree of protection will focus on safeguarding cultural value as a priority: - restoration of interior elements considered valuable including restoration of elements affected by previous interventions; - the removal of partitions which affect the cultural integrity of the inner spatial configuration; - restoration of the facades and their decorative components; - in the case of elements whose proportions have changed over time through non-professional interventions, it is mandatory to return to the original form; - restoring facade finishes in respect of the original image, where they have been aggressively replaced; - removing all unsuited elements and replacing them, where appropriate, with discrete and appropriate contemporary elements from the environmental and urban point of view; - removal of all secondary constructions
The proportion of the safeguard and development works ratios will be determined by the historical studies and interventions will be within the limits set out, namely: - restoration of interior elements with cultural values including restoration of elements affected by prior interventions; - the removal of partitions which affect the cultural integrity of the interior spatial configuration; - restoration of the façades affected by interventions prior to the study; where plastic decorations can be identified by means of historical documentation or analogies it is mandatory to restore them, but it is appropriate to highlight the lack of the original substance by discrete markings; - in the case of voids whose proportions have changed over time through non-professional interventions, it is mandatory to return to the original form; - restoring facade finishes in respect of the original image, where they have been aggressively replaced; - removing all destructuring elements and replacing

L/D Bulk density (kg.m-3) Dust content (mass%) Hemp shiv 6.3 73.6 0.32 Common reed 3.4 70.9 3.17 2.3 Water absorption Protocol to measure water absorption is also based on the recommendations of the RILEM (Amziane and Collet, 2017).
For each formulation, three thermal conductivity measurements are made after storage under standard conditions. 3 RESULTS AND DISCUSSIONS 3.1 Water behaviour Hemp shiv absorbs more than 360 % of water, while Phragmites reed absorbs less than 200 % of water with slower kinetics.
These results are too low to validate Phragmites australis based formulations for application in insulating concrete according to the professional rules of hemp construction (Règles professionnelles d’exécution d’ouvrages en béton de chanvre, 2010b).
This character is confirmed by water absorption tests on the aggregates where reed absorbs half as much water as the reference.
Indeed, the cohesion of the earth on the aggregates is achieved by evaporation of water.

Based on the illumination requirements (e.g. universal lighting, spot lighting and situational lighting) of different areas, the natural lighting is controlled and applied, and artificial illumination is set and integrated according to the basic composition principle of optical system and professional lighting design approach, thus finally achieving the goal of independent exhibition design by students.
In addition, professional industrial experts were invited to offer a detailed explanation on the types, application ranges and prices of artificial illumination lamps.
Design basis The initial curriculum design of “Exhibition Lighting and Illumination Design” accomplishes site planning, architectural modeling, traffic route, entrance and exit setting, function division, scale requirement, fire protection and water drainage.
