Portlandite is consumed by FA or MK to form C-S,Al-H.
Figure 7: Proportion of Al species obtained by 27Al MAS NMR.
Al(IV): aluminum substituted for silicon in C-S-H chains and residual anhydrous cement.
Al(V): aluminum substituted for calcium in the C-S-H interlayers or present in non-hydrated phases or in MK.

Gorla et al. [17, 18] lead a study on enhancing the convective heat transfer characteristics of nanofluids over bodies embedded in porous media.
Al-Odat and Al-Ghamdi [32] presented a two-dimensional steady double-diffusive free convective flow over a vertical plate in a saturated non-Darcy porous medium in the presence of magnetic field, Soret and Dufour effects.
Recently, Seth et al. [38] analyzed MHD free convective radiative nanofluid over a stretching sheet with combined effects of Soret and Dufour.

Aboshi et al. [4] reinforced the top portion of the column with a steel skirt.
The deep mixing method was used by Rashid et al. [5].
Different approaches have been proposed to stabilize sabkha soils, in particular the use of chemical and mechanical processes (Akili et al. [28], Abduljauwad and Al-Amoudi [29]).
Problem Definition of Locally Weak Zones (LWZ) Field reconnaissance in Chott el Hodna in Algeria has shown that locally weak zones are mostly circular in shape [31] as shown in Fig. 1a.

AL-Hamadi et al. [7] found that increase in free stream turbulence intensity has caused a significant reduction in the local film cooling effectiveness but increase in Stanton number.
Problem Statement The flat-plate film cooling with a cylindrical hole geometry is simulated based of Hasn Nasir et al [20], Kohli et al [21].
. [25] and kohli et al. [26] are shown in Figure 5.

Meanwhile, the effects of steel fibres on the behaviour of headed stud shear connectors of the composite beam were reported by Lin et al.[3].
The finite element approach in an innovative manner in terms of loading rates on the composite beam with profiled plain concrete flange was reported by Bavan et al [4].
Reviews of experimental specimen characteristics, analysis and results The test programmes executed by Vasdravellis et al. [1] and Nie et al. [2] involved in a steel-concrete composite beam with plain concrete flanges are reviewed in this study.
The experimental set-up was executed by Mpegetis et al. [5] for determining the behaviour and design of the steel fibre reinforced concrete slab.

In the past we have already grown LDH (Zn,Al) nanostructures on Al sheets [1-2] using in situ growth.
LDH (Zn, Al) intercalated with Cl-(a) and NO3-(b) anions.
Xu et al. [8] and Yoon et al. [9] have in fact shown low cytotoxicity towards cells, resulting non-toxic even at concentrations equal at 1 mg/mL.
LDHs grown on Al (see.

The recovery of the sediment for the manufacture of cement is done by Semcha [2], it studied the possibility of reusing the sludge collected in the solid state in the discharge area on Oued El Hamman and in the Macta region for the manufacture of cement.
The general valuation methodology described in the aims to use the dredging sediments from the Cheurfas dam in a formulation of road material by Bourabah and al [3].
There is also a natural stabilization with blood studied by Aymerich and al [10].
Then crushed and finally passed through a 5mm sieve to eliminate the large lumps according to Mahdad and al [9].
The blocks stabilized by cement give a low weight loss compared to those stabilized with lime, tis finding confirms the conclusions made by Guettala and al [12] and Mahdad and al [9].
