Hi, I hace several time trying to paginate (or create an infinite scroll) in my website http.//joseavila.com but the pagination just load the same posts and iv’e try anything but don’t find solution yet.

here’s the code:

<?php /*Template name: loop*/ ?>
<?php get_header(); ?>
<div id="content">
  <header>
    <i class="material-icons menu" data-toggle="aside">menu</i>
    <div class="mob-head">
      <h1><?php echo $blog_title = get_bloginfo('name'); ?></h1>
      <p>Fullstack Designer</p>
    </div>
  </header>
  <div class="content-wrap">
    <div class="loop">
      <?php
        rewind_posts();
        $paged = (get_query_var('paged')) ? get_query_var('paged') : 1;
        $args = array('post_type' => 'post', 'paged' => $paged);
        query_posts($args);
      ?>
      <?php if ( have_posts() ): ?>
      <?php while ( have_posts() ) : the_post(); ?>
        <?php $cat_id = $category->cat_ID; ?>
        <article class="item <?php echo 'cat-' . $cat_id;  ?>">
            <div class="img-holder">
            <i class="material-icons share">share</i>
              <figure>
                <a rel="<?php the_ID(); ?>" href="<?php the_permalink(); ?>"><?php the_post_thumbnail(); ?></a>
              </figure>
              <a class="titulo"rel="<?php the_ID(); ?>" href="<?php the_permalink(); ?>"><h2><?php the_title(); ?></h2><p> <i class=" cat-ico <?php echo do_shortcode('[cat_ico]') ?>"></i><?php foreach((get_the_category()) as $category) { echo $category->cat_name . ', '; } ?></p></a>
            </div>
            <section>
              <p><?php the_excerpt(); ?></p>
            </section>
            <a href="<?php the_permalink(); ?>"><div class="boton">
              <button>Ver más</button>
            </a>
            </div>
            <div class="sharing">
              <?php echo do_shortcode('[social_share]');?>
            </div>
        </article>
        <?php endwhile; ?>
        <div class="navigation">
          <div class="alignleft"><?php next_posts_link('&laquo; Older Entries') ?></div>
    			<div class="alignright"><?php previous_posts_link('Newer Entries &raquo;') ?></div>
        </div>
        <?php else : ?>
        <p><?php _e('Disculpa, nada que ver aqui.'); ?></p>
        <!-- navigation -->
      <?php endif; ?>

    </div>
    <!-- post-holder -->
    <div id="p-holder">
      <i class="fa fa-times-circle-o close" aria-hidden="true"></i>

      <div class="holder">
