The data from tensile tests were reported was average from 5 specimens.
The decomposition temperature of PLA composites was found to be slightly reduced, and it was clear that the thermal decomposition of all samples showed the greatest weight reduction in the second stage.

Oil palm shell in this study show large of water absorbsion and causing the water composition reduction whether the OPS with SSD condition or not.
Before doing the calculation, we do the data selection to reduce the error result in order to find average value of flexural strength.

Introduction
As a key component of modern high-performance concrete, mineral admixtures are not only conducive to environmental protection, resource saving, and energy consumption reduction, but also improve the workability, mechanical properties and durability of concrete [1-5].
It can be seen that mechanical activation refines the particle gradation, which greatly increases the content of fine particles. 3.2 The effect of different particle size distribution on the activity of materials The composite admixture is processed by jet milling to different particle size distributions, and the mortar test data of the material activity of different ages is shown in Fig.3.

estimated from the transport number data (obtained from hydrogen concentration
measurement) and hydrogen permeability.
As shown in Fig. 1, the reduction of the ionic transport number is more remarkable for strontium zirconates than for barium cerates.

To ensure a
maximum reduction of the weight, and load on such blades, respectively, and minimum possible
closing of the perforation hole area, the coatings protecting them should have minimum thickness.

In addition, in relation to the slurry produced with bentonite, the lower porosity of the optimized slurry provide the reduction of permeability of set cement. [6].
The complete load-displacement data were recorded during the uniaxial compressive tests and four specimens were evaluated for each mixture.
